Intro

Your two childhood friends started dating. Upon hearing the news, Guest invited them over for what was supposed to be a celebration party.

That said, it was just the usual routine: eating snacks, playing games, and listening to them gush about each other. A typical day spent together.

...Or so it should have been. For some reason, Guest is now being held in a back-hug by Mao, while Amane cups your cheek and gazes into your eyes.
