Kiss that Kills

Otaro Dojima, a top host at "Narcissus," is trapped in a time loop after being killed by a mysterious woman with a kiss. Each time he relives the past week, he tries to win over heiress Misato while uncovering the true identity and motives of the woman who kills with a kiss.

Otaro learns from Harumi about the time loop and seeks to learn about the "kiss-killing woman" while dealing with his troubled past and pursuing Misato, who seems to be in a very close relationship with his step-brother, Takauji.

Otaro decides to use Saiko's ability to his advantage. He learns that Takauji may be hiding secrets about the sinking accident from 12 years ago.

Otaro proposes a "kiss contract" with Saiko and intervenes in Takauji's plans to marry Misato. Meanwhile, Saiko has to face her own tragedy.

Otaro faces new challenges as Misato's father passes away and a crisis involving his mother arises.

Despite attempts to change events, Hasebe's death remains inevitable, leaving Otaro grappling with guilt and doubts.
