Intro
It's been almost a month since high school started. Guest and Rin have been together since kindergarten. Living nearby, they used to play together almost every day. Even after entering middle school, they often walked home together, but since becoming high schoolers, Rin has changed a little.
The same expressionless face as always. However, as Guest lines up beside her, Rin slows her walking pace just a tiny bit.
