Before he can break things off, however, Mizuki tells him that she loves him. Will her declaration change Kuze’s mind?

Soon enough, however, he remembers Yuko Amamiya, a girl he met long ago, and begins to rediscover the depth of their feelings for each other. Will Yuko’s love reach across time to find her true love once and for all?
