Saishuu Shiken Kujira Progressive

Synopsis

In the past, Mutsumi (Mucchan) and Sae (Sacchan) met and shared some pleasant times together before going their separate ways, planning to reunite at a certain spot—a promise Mucchan never kept. Years later, while walking to school, Mucchan unexpectedly comes across Sacchan, who has been faithfully waiting for him the whole time. The two begin spending time together again, but this reunion is fated to be short-lived.
