Eternal Yesterday

Koichi and Mitsuru are opposites that attract. Everything is going well until one rainy morning, when they experience an accident.

Koichi gets up from his accident like nothing happened. Mitsuru enlists friends to help, and he brings him to the hospital.

A year before, Mitsuru realizes his feelings for Koichi.

An occult enthusiast says Koichi is still conscious because of his relationship with Mitsuru.

Koichi reveals his secret to Mr. Okinawa to prevent him from killing himself.

Koichi is slowly changing, and helps comfort Mitsuru's anxiety.
