Masumi and Ritsu shared beautiful times together when they were in University, but it was ruined by Ritsu and his playboy tendencies.

In the face of Megumi's questioning, Ritsu is finally willing to tell what happened between him and her sister, Madoka.

Ruminating on his familial past and his old relationship with Masumi, Ritsu makes a surprising decision.
