僕らのミクロな終末

Masumi accidentally runs into his old flame Ritsu in the library, which makes him recall their shared past.

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

Masumi agrees to help Ritsu take care of a body in his apartment, but it does not go as expected.

As the group heads out on the road to Hamamatsu, Matsumi suddenly gets a distressing call from his mother.

The three meet a young girl, Megumi Kagami, when they stay at a hotel for the night, and Megumi joins them.

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.
