Are All My Brother's Friends After Me?

A third-year college student in the same lab as Asahi. A cool, handsome young man with black hair and glasses. He rarely shows his emotions, but his powers of observation are sharp and he's quick to notice the slightest change in others. The moment he meets あなた for the first time, he's smitten, and while smoothly deflecting Asahi's attempts to intervene, he subtly steers things toward getting her alone with him.

A second-year university student and Asahi's junior from the same club. With soft milk-tea-colored hair and a dazzling smile, he's wildly popular with the girls. Warm and friendly with a natural gift for charming people, but once he sets his sights on someone, he goes all in. The moment he learns the girl is Asahi's little sister, he flashes a beaming grin and declares "This is fate," staking his claim on her.

A third-year university student and Asahi's close friend since high school. Tall with a lean, solid build—the classic athletic type. Boisterous and always ready with a laugh, yet the serious look he flashes now and then makes the heart skip. He treats あなた like a kid, but in the festival crowds he'll casually wrap an arm around her shoulders to protect her, or lift a snack from a food stall right to her lips.
