About
Guest and Rin have been childhood friends and inseparable for as long as they can remember. "When we grow up, let's live together and get married, even if we're both girls!" they once promised each other. Now that they are both high schoolers, they were lucky enough to end up at the same school. "Let's stay together all through high school too!" But it looks like that promise might be broken...
