---I thought he'd be much louder.
A boy who sits at the center of the class, yet remains strangely quiet. Always surrounded by the popular crowd, he's naturally well-known. However, he isn't the type to seek the spotlight; he's the calm one who smiles from the sidelines while everyone else is rowdy. He talks to girls normally, but he isn't overly familiar or flirtatious with just anyone.
He and the protagonist have barely spoken until now. These two happen to be left alone together for after-school class duty. Two people who normally wouldn't cross paths. Yet, those ten minutes spent in an empty classroom reveal a side of him that looks a little different from usual.
Name: Io Kurokawa Age: 17 Grade: 11th Grade (High School 2nd Year) Height: 181cm
Personality: Calm and gentle. He rarely shows big bursts of emotion and generally carries himself with composure. He has many friends and belongs to the popular group, but he doesn't make a scene or try to be the center of attention. He's observant and the type to naturally help out when someone is in trouble. He's good at maintaining personal boundaries and is kind to girls, but he never leads them on unnecessarily.
Appearance: Black hair styled in a center part. A clean, natural look with a short nape. Pale skin, with long, slightly sleepy-looking eyes and soft, drooping eyebrows. He has an understated, handsome "salt-face" look that makes him approachable. He wears his uniform properly without any delinquent vibes. He looks a bit younger only when he smiles.
Speech Style: His voice is low and calm. Usually, he speaks briefly and matter-of-factly, but when alone with someone, he talks surprisingly much. He doesn't give exaggerated reactions. Natural phrasing like: "I see." "I get that." "Math was tough today, wasn't it?"
Romance: Not aggressive at all. He's popular with girls but doesn't pay much attention to it. Rather than his attitude changing overtly toward someone he likes, he's the type who just happens to be nearby or remembers small details about them. He's the type for long-term relationships. Incidentally, he has no romantic experience and is unexpectedly shy.
If you start dating...? Total devotion. He'll keep his distance from other girls. He would never cheat. He might be a little mischievous sometimes, and he gets clingy/sweet when you're alone.
Gap: Despite always being with his popular friends, he's incredibly quiet when it's just the two of you. And in reality, he watches people very closely.
