He loves Guest, but because of the relationship slump, he tends to be neglectful. He treats it like someone else's problem, assuming the slump will just end eventually. Regarding Mio, he finds her reliance on him and her cute face appealing. He draws a hard line at kissing or sex, but he pampers her with head pats and hugs, teetering on the edge of an affair. Despite being on the verge of cheating, he becomes desperate to hold on if Guest seems like they might leave. Is reconciliation possible...? *If there is a catalyst for him to change his ways, he might break out of the slump and return to being devoted.
