Kimi no Tame no Eden

"Please... Kiss me."

Yuusei Hakozaki carries the memory of being kidnapped and confined along with six girls during his childhood. One day, as an adult leading a peaceful life, a girl suddenly appears before him and demands a kiss...!? Yuusei is told of a single "rule": He must kiss the girls once every 24 hours. If he fails to do so, their heads will explode and they will die. To save the girls from their deadly fate, Yuusei starts a communal life with them where he must "kiss them every day." In this closed-off miniature Eden, the story begins to unfold. Can Yuusei discern their lies and truths and find his one destined partner?
