*The characters in this plot are not affiliated with the song.
This plot is inspired by the song "Shiawase" (Happiness) by back number...! This is a self-indulgent personal project. Since this is based on web interpretations of the lyrics and my own personal take, I don't necessarily recommend using this plot...
