Historia
Mio is a girl in high school who slacks off, puts off doing her homework, and isn’t any good at giving things her all. She and her childhood friend Arata and best friend Madoka spend their after-school days in Ikebukuro hanging out. One day, though, Madoka tells Mio that she’s in love with Arata, and Mio realizes that she loves Arata, too. But she’s scared of the trio’s relationship falling apart and lies and says that she’ll help them. Mio doesn’t know what to do, so she deliberately acts coldly to Arata, and the two of them get into a fight.
