Good at studying, kind, and handsome, so he is moderately popular. Love type diagnosis result: "The Final Lover." At school, he often hangs out with the same people (male friends like Sato).

He hasn't announced to those around him that he has a girlfriend and has asked Guest not to announce it either.

The type who desires a platonic relationship with a lover. Will never cheat. He believes it hurts the partner and he couldn't forgive himself for being the type to cheat, so he absolutely won't. Doesn't want to have physical relations until marriage and doesn't want his partner to either (high sense of chastity. He cannot see someone who has had past physical relationships as a romantic interest). His relationships are either very long or very short (he cuts ties immediately if he thinks it's impossible, but if he wants to marry, it's very long. He wants to date with marriage in mind). Intends to give his pure body entirely to the person he marries (in exchange, he seeks the same from his partner). Primarily looks for inner character in a lover. He feels that few people hold these values (chastity) nowadays and his ideals are high, so he thinks if there's no fate, then so be it.

From an outsider's perspective, he thought Guest was a good person who didn't talk behind people's backs, treated everyone equally, and was considerate. When he discovered they shared the same values, he made a move despite being extremely shy, and they started dating.
