Who Will Grow Old With You

Gu Yunsheng is reborn on the day she must choose a husband. In her past life she chose Qi Mohan, who faked his death and betrayed her. When her grandfather asks again, she refuses Qi Mohan and points to someone else.

Gu Yunsheng writes Duan Qingye's name on the marriage contract, telling her grandfather that Duan will build a tech empire and be a capable partner. She asks to keep it secret until the engagement banquet. Qi Mohan rejects her outright, but she recalls he did not refuse her in the past life and suspects he may be reborn too.

Qi Mohan publicly declares his heart belongs to Lin Weiwei and refuses to be the fiance. Gu Yunsheng coldly retorts she never meant to choose him and demands he repay the Gu family for years of support. She announces she will name her true fiance at an engagement banquet in seven days.

Qi Mohan assumes Gu Yunsheng will still choose him, but she denies it. She invites Duan Qingye to the engagement banquet in seven days. He coldly declines, saying he will send a gift but not attend. Gu Yunsheng is amused, since he is the intended fiance.

Gu Yunsheng plays the pipa on campus. Nearby talk between Lin Weiwei and her maid stirs a memory. She realizes the pipa piece Qi Mohan fell for at the orientation party was actually played by her — and he mistook Lin Weiwei for the musician all along.

Gu Yunsheng demands Qi Mohan return her pipa, which he took without permission. Lin Weiwei deliberately lets her dog approach Gu Yunsheng, triggering a severe allergy attack. Lin Weiwei seizes Gu Yunsheng's medicine and threatens to withhold it unless she refuses Qi Mohan at the engagement banquet, while Qi Mohan continues to defend Lin Weiwei.

Gu Yunsheng wakes in hospital to learn Duan Qingye brought her there and left her special asthma medication. Qi Mohan storms in, drags her away, and forces her to give a large amount of blood for Lin Weiwei, ignoring her wellbeing. Afterward, her maid Xiaoyu condemns Qi Mohan's ingratitude, and Gu Yunsheng reveals she never chose him as her husband.

Qi Mohan demands Gu Yunsheng's only artificial heart to save Lin Weiwei. Her maid Xiaoyu protests, but Gu Yunsheng sets three conditions: kneel in the Gu family shrine for three days, never go back on his word, and attend the engagement banquet. Qi Mohan agrees to all.

Gu Yunsheng casually tells Xiaoyu to store a rare jade that treats asthma. Duan Qingye recognizes it as a gift she painstakingly sourced and says he likes it. He claims he cannot attend the engagement banquet tomorrow, but when she insists, he asks if she fears he will crash it — and she replies that if he dares, she will leave with him.

The Gu family offers a lavish dowry, but Qi Mohan publicly declares he only agreed to marry Gu Yunsheng to secure an artificial heart for Lin Weiwei. Gu Yunsheng interrupts the speculation, describes her childhood sweetheart, and then names Duan Qingye as her fiancé.

Guests assume Gu Yunsheng's fiancé is Qi Mohan, and Qi Mohan himself mocks her, insisting she would never choose anyone else. Gu Yunsheng flatly denies calling his name and, when no one believes her, asks her grandfather to bring out the marriage contract.

The crowd presses Gu Yunsheng to reveal the name on the engagement letter, doubting she would really abandon Qi Mohan. She insists on writing it herself and orders the letter projected onto the big screen for everyone to see.

Gu Yunsheng announces to the crowd that she will no longer cling to Qi Mohan and that her fiancé is Duan Qingye, the man who always clashed with her yet was the first to protect her in danger. Amid disbelief and accusations that she is merely saving face, she asks her grandfather to confirm that Duan Qingye will jointly lead the Gu Group with her.

Guests doubt Gu Yunsheng's choice of Duan Qingye, calling it a staged act. Qi Mohan urges her to stop talking nonsense. She produces the contract from when the Gu family adopted him, cites his broken promises of loyalty and marriage, then tears it up and sets him free to be with Lin Weiwei.

Gu Yunsheng tears up the adoption contract in public. Qi Mohan accuses her of madness and doubts her sincerity, but she insists she will only marry Duan Qingye. When Qi Mohan mocks Duan Qingye as a dissolute playboy, Duan Qingye steps in and declares he will not let his fiancée think of any other man.

Duan Qingye warns Qi Mohan to stay away from his fiancée. Gu Huaiyuan entrusts Gu Yunsheng to Duan Qingye, who vows to prove her choice right. In private, Duan Qingye assumes she picked him out of spite, but Gu Yunsheng insists he is the better man and asks if he is unwilling to marry her.

Gu Yunsheng and Duan Qingye register their marriage. He asks repeatedly if she is sure, and she says marrying Qi Mohan in her past life was her true regret. Duan Qingye's attendant reveals he is the heir to a powerful family, who hid his status and stayed in Jiangcheng for her.

Gu Yunsheng announces on trending searches that she will hold a wedding with Duan Qingye in half a month, and that Gushi Group will enter a new phase with his help. Qi Mohan sees the news but dismisses it as her acting out of jealousy over his closeness to Lin Weiwei, refusing to believe she would marry a man he considers worthless.

After clearing the room, Lin Weiwei proposes to Qi Mohan. He deflects, claiming he fears Gu Yunsheng will change her mind and force him into marriage. Lin Weiwei accuses him of simply being unable to let go of Gu Yunsheng.

Lin Weiwei asks Qi Mohan if he will marry her. He promises to take responsibility and suggests they get engaged soon, telling her to pick a diamond ring at an auction the next evening. Meanwhile, Gu Yunsheng learns that her parents' treasured pipa, Everlasting Longing, will appear at the same auction and resolves not to miss it this time.

Gu Yunsheng and Duan Qingye run into Qi Mohan and Lin Weiwei at the auction entrance. Lin Weiwei flaunts her engagement, while Qi Mohan announces they are there to pick a wedding ring and will soon be engaged, bringing up Gu Yunsheng's past refusal to trade an artificial heart for marriage.

At the auction, Qi Mohan bids thirty million for a pink diamond for Lin Weiwei. Duan Qingye suddenly joins the bidding, declaring it is for his fiancée Gu Yunsheng, and raises the bid to one hundred million.

The auction's final lot is a red sandalwood pipa named Chang Xiang Si, once a token of love between Gu Yunsheng's parents. Seeing it stirs memories of her mother teaching her to play and entrusting her with its jade. When Qi Mohan bids seventy million for Lin Weiwei, Gu Yunsheng counters with eighty million.

Qi Mohan accuses Gu Yunsheng of being with Duan Qingye out of spite, while Lin Weiwei mocks her. The auction house announces that, per her mother's will, the winning bidder must perform on the pipa. As the crowd anticipates Gu Yunsheng's performance, Lin Weiwei panics, fearing her secret from the welcome party will be exposed.

Lin Weiwei's maid claims Gu Yunsheng cannot play the pipa, and Qi Mohan urges her to give it up. Gu Yunsheng retorts that Qi Mohan never truly knew her and insists on performing to prove the pipa is hers. Duan Qingye asserts his control over the auction and allows her to take the stage.

Gu Yunsheng takes the stage and plays the pipa, silencing the room. As she performs, she recalls childhood memories of her mother teaching her and Duan Qingye practicing with her. After the piece ends, Duan Qingye orders everything he won at auction delivered to the Gu residence.

Duan Qingye is mistaken for the crown prince by a staff member but brushes it off and leaves with Gu Yunsheng. Elsewhere, Qi Mohan tries to pay for Lin Weiwei's purchase, only to find that the supplementary card from Gu Yunsheng and all his accounts have been frozen.

Gu Yunsheng orders Xiaoyu to cancel all the supplementary cards she gave Qi Mohan, saying he used her money to bid on a wedding ring for Lin Weiwei at the auction. Qi Mohan finds his accounts frozen and assumes she is jealous and sulking. Lin Weiwei suggests they connect with a capable aide of the Bo family's crown prince to make money.

The executive introduced by Lin Weiwei offers funding through a bet-on agreement, demanding Qi Mohan repay three times the principal plus interest in one year. Qi Mohan hesitates but signs, and Lin Weiwei urges him to earn quickly for their engagement banquet. Gu Yunsheng receives the invitation and decides to attend in person with a prepared gift.

Gu Yunsheng arrives at Qi Mohan and Lin Weiwei's engagement banquet with a prepared gift. Duan Qingye reminds her that she is a married woman. Guests gossip about the couple, while Lin Weiwei gloats that she will soon be Mrs. Qi.

Gu Yunsheng appears at Qi Mohan and Lin Weiwei's engagement banquet. Guests wonder if she has come to cause trouble. Lin Weiwei begs her not to interfere, but Gu Yunsheng says she has already let them go and only wants to ask Qi Mohan a few questions.

Gu Yunsheng confronts Qi Mohan, asking why years of devotion earned no affection from him. Qi Mohan admits he fell for Lin Weiwei at the welcome party because she played the pipa. Gu Yunsheng then challenges Lin Weiwei to perform on the spot so the guests can judge the music that supposedly captivated him.

Guests urge Lin Weiwei to play the pipa and prove the love-at-first-sight story Qi Mohan told. Gu Yunsheng questions whether Qi Mohan actually saw Lin Weiwei play that day. Qi Mohan and Lu Min push Lin Weiwei to perform and put an end to the doubt.

Lin Weiwei's pipa performance is full of basic mistakes, and guests openly mock Qi Mohan's love-at-first-sight story. Gu Yunsheng points out the technical errors in her fingering and tuning. As Qi Mohan and Lu Min push back, Lin Weiwei panics, terrified her secret will be exposed.

Qi Mohan and Lu Min goad Gu Yunsheng into performing, insisting she should play if she truly understands the pipa. She accepts the challenge, approaches the instrument, and confronts Qi Mohan about his love-at-first-sight story, announcing she will play the very song from that night.

After Gu Yunsheng finishes playing, guests recognize her as the mysterious pipa player from the welcome party years ago. Qi Mohan is stunned to realize the woman he loved across two lifetimes is not Lin Weiwei, but Gu Yunsheng.

Qi Mohan is stunned to learn he mistook Lin Weiwei for the pipa player. When he demands to know why Gu Yunsheng never told him, she points out that as the Gu family's foster son, his pride never allowed him to love her.

Qi Mohan admits his pride kept him from loving her and now realizes Gu Yunsheng is the one who moved his heart. He begs to begin again, but she reminds him she is already engaged and invokes the condition he once agreed to — never to go back on his word.

Qi Mohan begs for forgiveness and promises to make amends, but Gu Yunsheng declares her engagement to Duan Qingye is final and wishes him freedom. A memory surfaces of her as a child leaving Qi Mohan a letter with a promise to marry him in ten years.

Late at night Qi Mohan forces his way into the Gu house, demanding to see Gu Yunsheng and declaring he will not let her marry another man. Gu Huaiyuan confronts him, recalling the promise Qi Mohan made when he was taken in — to treat Yunsheng well — and the harm he has now caused her.

Gu Huaiyuan rejects Qi Mohan's apology, severs all ties with him, and orders him to leave the Gu house at once. Qi Mohan then stops Gu Yunsheng, trying to explain the impersonation, but she sees through him. She tells him she has scheduled heart surgery and demands he return the heart that belonged to her.

Lin Weiwei refuses Qi Mohan's plea for an artificial heart, pointing out he has been lost ever since Gu Yunsheng did not choose him. She says his heart has always belonged to Gu Yunsheng. Qi Mohan then begs Gu Yunsheng for forgiveness, and Lin Weiwei mocks him, offering to give up her fiancée status if he cannot let go.

Gu Yunsheng hesitates for ten seconds before blocking Qi Mohan, and Duan Qingye calls her out on it. When his ears turn red and he makes an excuse to swap her water, she teases him about being jealous. A call then arrives about an urgent delivery, and she steps out alone.

Duan Qingye realizes Gu Yunsheng has been gone for twenty minutes. Xiaoyu finds her phone, and Duan Qingye orders an immediate search. Meanwhile, Qi Mohan receives a call reporting that Gu Yunsheng was seen being helped into a hotel elevator by a strange man, and the caller sends him the hotel's location.

A strange man brings Gu Yunsheng to a hotel room and declares he will kill her tonight. She warns that the Gu family will not let him live, but he ignores her and closes in.

A stranger threatens Gu Yunsheng, but Duan Qingye arrives in time, shields her, and warns the man off. He then takes her to the hospital, where a doctor announces the patient is awake and family may enter.

Duan Qingye enters the hospital room. Qi Mohan claims Gu Yunsheng's attack was orchestrated by Duan Qingye's girlfriend and urges her to divorce. Duan Qingye replies calmly that he will sign the papers the moment she asks, leaving the choice entirely to her.

Gu Yunsheng tells Qi Mohan plainly that she will never divorce Duan Qingye and asks him to leave. She then tells Duan Qingye she wants to go home with him to their marital house and asks him to cook her braised beef in red wine.

Gu Yunsheng returns home with Duan Qingye and finds he has personally arranged the flower room and filled the house with gifts. He blindfolds her and leads her into the bedroom, where everything from the dark green sheets to the walnut furniture matches her taste. She asks how he knows what she likes and teases that he must have secretly loved her.

Looking at the bridal room Duan Qingye has arranged, Gu Yunsheng recalls that in her past life she was devoted to Qi Mohan and overlooked the one who truly cared for her. She thanks Duan Qingye, then asks where he got the money for such expensive furniture.

Gu Yunsheng presses Duan Qingye about the money he spent at the auction, but he tells her it only matters that he can earn. She recalls how in her past life he became a powerful figure in the capital within three years and accepts his answer. He then declares that all household chores will be his alone, and she happily agrees.

Duan Qingye takes a call from his mother, who has already arrived downstairs with a large entourage, demanding to meet her daughter-in-law. He tries to stop her, but she barges in just as he is seen pulling another woman aside.

Duan Qingye's mother waits downstairs with lavish gifts, insisting on meeting Gu Yunsheng. He stops her, explaining that he has never revealed his wealthy background and fears she will scare Gu Yunsheng away. Reluctantly, she agrees to hold off for now.

Duan Qingye and his mother agree to reveal his identity and propose at the Gu family banquet in three days. To show sincerity, she insists the bride price be ten times what Gu Yunsheng's father once offered, and hands him a priceless vintage Maotai to present to Grandpa Gu.

Qi Mohan and a companion spot Duan Qingye with his arm around an older, well-dressed woman flanked by bodyguards. Recalling Duan Qingye's extravagant bid for Gu Yunsheng at an auction, Qi Mohan questions where the money came from and concludes Duan Qingye is being kept by a wealthy woman. He resolves to tell Gu Yunsheng.

Qi Mohan tells his companion that Gu Yunsheng now trusts Duan Qingye completely and would dismiss any photo as an attempt to sow discord. He decides to publicly reveal the photos of Duan Qingye with the older woman at Gu Huaiyuan's birthday banquet three days later, certain that Duan Qingye will have no defense and that Gu Yunsheng will then return to him.
