Floral designer Vivian has been in a five-year relationship with wealthy heir Arthur. To get married, the Winston family requires an anonymous vote from its elders. A black ballot will delay the engagement and punish the heir. Feeling sorry for Arthur, who gets flogged every year, Vivian hopes all ballots will be white in their fifth year together. However, she accidentally catches Arthur dropping a black ballot into the box full of white votes. It turns out he does not want to leave his assistant Olivia, so he deliberately creates obstacles and fakes self-harm to gain Vivian’s sympathy.
The truth shatters all Vivian’s hopes. She blocks Arthur, sells her long-running floral studio, and wipes away every memory they shared. Adrian was saved by Vivian from a fire years ago and has watched over her in secret ever since. He proposes a marriage alliance, and Vivian accepts. They travel to San Francisco to register their marriage.
Upon hearing the news, Arthur rushes frantically to win her back. He confronts Vivian at her wedding, but she draws a clear line with him in public. Later, Arthur uncovers all of Olivia’s schemes and drives her away. He endures severe family punishment to plead for reconciliation, yet Vivian turns him down firmly.
