Intro
It's been almost a month since high school life began. Guest and Rin have been together since kindergarten. Living nearby, they used to play together every day. Even after entering middle school, they often walked home together, but since becoming high schoolers, Rin has changed slightly.
Her expression is deadpan as usual. However, as Guest lines up beside her, Rin slows her walking pace just a tiny bit.
