I did not molest her, she is your sister...".

Keiko (Yoshitani Ayako)'s fiancé Haruki (Miura Takahiro) was arrested on suspicion of sexual harassment in the train.It was her sister Shiho (Rina Asakawa) who made the accusation... Of course, this was fabricated to destroy Keiko's happiness.

Keiko rushed to the station after receiving the notice, and was asked by Shiho to apologize:“ If you apologize seriously here now, I won't call the police.”.“As long as he apologizes... he will be let go, right?”.Although Keiko was trembling from the unprecedented humiliation, in order to save Haruki, she still knelt down in front of Shiho and apologized - “I'm sorry”.

“It's all my fault, it's my sister who...”.Keiko felt heartbroken about being implicated in Chunxi, and broke up with Chunxi who was released.“As for the marriage, just pretend it never happened”.So Chunxi accepted the breakup frankly: "I don't have the confidence to get along well with you sisters anymore".Shiho smiled mockingly after hearing this, and then in order to further attack the two, he spread a video of Keiko kneeling down to apologize.Therefore, both Keiko and Haruki were fired from the company, and their cohabitation and engagement were cancelled... Keiko, who seemed to have suffered failure, has not given up “happiness” yet!You have to seize your own happiness... My sister's heroic revenge plan has begun!!
