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.
Encouraged by Saiko's words, Otaro resolves to mend his broken family ties. Meanwhile, Takauji suspects Saiko of having predictive abilities and kidnaps her, leading to a tense confrontation.
