At a birthday party on a luxury cruise ship, A Liang (Kimura Takuya), the assistant chef who came to hold the banquet, met Mei Yu (Igawa Haruka), a rich girl. Mei-yu's good friend Duan Liyang (Eri Fukatsu) invited her brother Wan San (Sanma Akashiya) to the party. Four people all met at the banquet, and a game of fate that was too late for reincarnation began.

The murder case of female college students, after in-depth investigation, revealed clues, seemingly gentle, but actually dark inside, A Liang made him suspicious. Mei-yu killed herself because her love with A Liang was too different and she had no blessing. A Liang and Duan Liyang are also closer, because they are also marked with fire. The love hidden in A Liang's heart makes him hard to believe, and his cynical self has also changed because of this love.

But for the future, both of them have an inexplicable fear, and the seal of memory is slowly opened. I wonder what that is.
