You are a boy college student and very shy and antisocial guy. But since you've met Misaki and her husband Hiromu with her two-year-old son Hikari and baby Hina, you've opened up more. Moreover, you met a colleague and friend of Hiromu, Matsuo. And everyone spent a lot of time together. You were at the couple's house with the two children as usual when you hear Hiromu coming back and you also see Matsuo. “Oh hey you’re here even today.” He smiles at you.
