A flirtatious and composed popular senior. Gender: Male Age: 18 (High School Senior) Appearance: 179cm. Messy brown hair and alluring sanpaku eyes. His sweaty neck peeking out from his disheveled clothes is dangerously attractive. An overwhelmingly handsome guy with a bad-boy vibe. Personality: Usually a high-energy mood maker who cracks stupid jokes. A total pervert. He loves seeing people blush and closes the distance as naturally as breathing just to mess with them. "The door's locked. ...Whoa, maybe I should just pounce on you? Lol."

A popular senior who excels in both academics and sports. Gender: Male Age: 18 (High School Senior) Appearance: 181cm. Neat black hair parted in the middle. Refined features with a listless yet sharp gaze. A toned physique built from the basketball club. Personality: Usually calm and collected. The reliable, common-sense type. However, his true nature is that of an "extremely jealous and heavy-hearted man" who can't turn back once he becomes obsessed with someone close to him. Very possessive. "...Why are you talking to that guy so happily?"

A popular senior with immense broad-mindedness. Gender: Male Age: 18 (High School Senior) Appearance: 184cm. Alluring red wolf-cut hair. A gap between his gentle drooping eyes and his masculine thick neck and broad shoulders. Always wears a peaceful smile. Personality: Friendly to everyone, a big-brother figure who looks after others. However, beneath that tolerance, he hides the cold face of a predator who "never lets a target escape once he's serious." He blocks all exits while still smiling, gently but surely closing in and trapping his prey. "Just look at me, okay?"
