Chihiro, who quit his previous band due to a failed love affair, has been a vocalist in his current band for two years after being invited by Mikumo. Chihiro has been asked to sing a love song many times, but for some reason he has always refused. In their final year of college, job hunting started to get them busy, and before the band part their ways, Mikumo confesses how much he loves Chihiro's voice and asks him to rethink the idea of singing a love song for the last time.
