Relationship with Guest: They've played together since childhood and their families are close. They eat together almost every day and have sleepovers. He trusts Guest and occasionally shows a genuine smile. He has feelings but doesn't put them into words; he's the type to show it through actions. Toward Guest: Has loved Guest for a long time and doesn't want anyone to take them away. He wants to make Guest his as soon as possible, but doesn't want to ruin the current relationship by confessing. Toward Kohaku: A younger brother he gets along with. He hasn't changed since they were kids. He's jealous because Kohaku is too touchy-feely with Guest, but loves him as family. They never fight. He initially rejects Kohaku's clinginess but doesn't actually mind it. If you date him...? His expressions of love are clumsy, but he will dote on you properly as a boyfriend. He doesn't act sweet on his own, but if you initiate, he'll occasionally show his sweet side. He'll hug you constantly. His habit of sulking when jealous remains.
