In flashback she remembers marrying Marcus in her previous life, then discovering he faked his death to elope with the maid Vivian and raise children. She confronts Marcus; a fire interrupts their fight and he says, "I only want to be with Vivian." In the present Grandpa presses her to name Marcus as fiancé. Yvonne refuses and declares, "I'll pick him," leaving which man she will choose unresolved.
At a family gathering with four suitors, Yvonne shocks everyone by choosing Quintus Dalton as her fiancé. Grandpa objects, calling Quintus a playboy and unreliable. Yvonne counters with a past-life memory: after she married him he left Riverton, founded the nation's largest tech company and became the richest man. She will soon graduate and run the family group; she asks Grandpa to keep the choice secret until her engagement party in seven days. Guests assume Marcus is the fiancé; a guest's public plea to pursue another love turns the secret into an immediate problem.
At a public gathering Marcus shocks the Grant family by refusing the arranged engagement and declaring he is in love and will defy them. Miss Grant — who warns, "In my past life... now it's your turn to suffer" — issues an ultimatum: the engagement party is in seven days and she will announce her fiancé herself. Yvonne begs forgiveness while Marcus offers to repay the family for raising him and pleads that Vivian not be punished. The Grants threaten to take the matter to court. The episode ends with a shouted, "Vivian!", leaving the seven-day deadline unresolved.
At a social gathering, Yvonne (Miss Grant) is told her fiancé has been decided and is ordered to be married in seven days; an associate summons Quintus to the engagement, but he refuses the title and offers only a lavish gift. Hurt and defiant, Yvonne tells Yara to throw away keepsakes tied to Mr. Quinn, calling them meaningless. She discovers her mother's pipa was given to Vivian by Mr. Quinn and vows to retrieve it. The episode ends with Yvonne determined to reclaim the pipa before the engagement, leaving the conflict unresolved.
Marcus is told he'll be Miss Grant's fiancé in seven days, and Vivian panics that she'll lose him. Marcus insists he still loves Vivian and proposes an elopement; Vivian suspects he plans to fake his death. He explains he was captivated by pipa music at the freshman gala and believed the player was Vivian. In class, Miss Grant plays the pipa and draws praise; a man confesses he's captivated and vows to marry her, revealing Marcus mistook the real pipa player for Vivian. With seven days until the engagement and an escape plan hinging on deception, Marcus faces a choice.
Miss Grant bursts in demanding her pipa after discovering it was given to Vivian. Marcus intervenes; Monica the dog is introduced and makes the allergic Miss Grant uncomfortable. The scene turns tense when someone withholds Vivian’s medication and admits she, not Vivian, played the pipa. She blackmails Miss Grant: if Miss Grant doesn’t choose Marcus at the engagement party in seven days, the meds stay withheld. A shove and shouted warnings follow, and Yvonne vows to retaliate if Vivian is harmed, leaving Miss Grant facing a pressure-filled decision before the party.
Miss Grant wakes in hospital after Mr. Dalton brings her in and learns her maid Vivian is bleeding heavily and critically injured—Vivian fell because of her. Doctors and staff say Miss Grant’s blood type matches Vivian’s; she’s already had 1,000 ml taken and they pressure her for more. Marcus admits taking drastic steps and insists he won’t regret it if Vivian survives. Guests angrily suggest Mr. Quinn has exploited Miss Grant, even as her wedding is seven days away. Miss Grant rejects the idea she picked that fiancé, leaving Vivian’s recovery and the engagement unresolved.
At the hospital, staff report Vivian's transfusion failed and she needs a heart; Yvonne (Miss Grant) owns the only artificial heart her father developed. Doctors and relatives plead to give it to Vivian, but giving it up would leave Yvonne without the device she needs. Marcus says he can secure the heart but imposes three conditions: kneel in the Grant ancestral hall for three days, never regret whichever fiancé he chooses, and attend his engagement party in seven days. Under pressure, Yvonne agrees, promising to be there—securing the heart but binding herself to the looming engagement.
Vivian, who has a heart transplant scheduled in a few days, leaves the hospital to see her fiancé Marcus try on his groom's outfit during pre-wedding fittings. At the boutique Yvonne's dramatic makeover steals attention while Quintus is conspicuously absent; others grumble they're just for show and 'only the fiancé Marcus matters.' A buyer insists cufflinks be embroidered with a 'Q,' sparking debate over Mr. Quinn versus Quintus and the buyer says, "It's for my fiancé." When someone warns Yvonne she could get hurt, a voice yells, "Watch out!" and the episode cuts on that alarm.
During engagement preparations a chandelier frightens Marcus; he clutches his chest and is urged to go to the hospital. Staff stash a valuable Cold Marrow Jade in the storeroom and note the fiancé’s gifts were hard-won, not accidental. Riverton assumes Miss Grant will name Marcus her fiancé at tomorrow’s party and guests praise his expected inheritance. Marcus rebuffs that by saying, "My heart belongs to Vivian." Someone promises to walk away with him if anyone stops the ceremony. Howard and granddaughter Yvonne Grant arrive, raising the stakes for the public naming.
