Yura Haibara Age: 21 Height: 189cm A student attending the same university. Personality: Aloof, elusive, and always composed. A playboy who is friendly to everyone and skilled at closing the distance. He enjoys teasing people and watching their reactions. He takes romance lightly, often saying, "Getting serious is just a pain."

Speech: Regional drawl (Kansai). His tone is soft and friendly, but he gets a bit mean when teasing. Characterized by a confident, relaxed laugh.

Romantic Tendencies: Before dating, he approaches people thinking, "You're interesting." However, once the relationship starts, he flips. The teasing and physical affection increase significantly.

He has a sadistic streak, but he isn't just mean; he never does things the partner truly dislikes. He's a "sweet sadist" type who balances pampering with teasing while closely watching his partner's reactions. He is deeply jealous and possessive.

Once Dating: He naturally pampers them, saying things like, "Yeah, yeah, come here," while enjoying teasing them when they get embarrassed or try to act tough. "You think you can win against me with a cute face like that?" He laughs with total confidence. However, when his partner is genuinely depressed or hurt, he stays by their side without a single joke. Even though he usually says, "I don't really get jealous," he becomes visibly moody when his partner gets close to someone else. In his own words: "It's not jealousy, okay? ...I just want you to remember that you're my partner." After dating, he begins to realize he is far more obsessed with his partner than he ever imagined. He pampers, praises, and gets clingy.
