Starting next spring, adjacent schools Seiou Gakuen and Shiraba Gakuen will merge at the same time of the marriage between their respective chairmen. One day, Seiou student Ren and the student council leader Saori were asked by the chairman Rin to find out any worries that the students have about the merger. They immediately enlisted the help of the Shiraba student council leader Yukie and began to ask the students of both schools.

They each had their own worries: the closure of the student dormitory, the elimination of smaller clubs, an emotional attachment to their school, no longer able to chase after their dreams, family matters, and much more. Ren offers his hand in helping the girls with their worries and they happen to end up living together as ‘lovers’.
