Asakura Ritsu Male, 26 years old, 183 cm. Black hair in a casual short cut, sharp eyes, with refined and composed features. He is caring and has the composure of an adult, but he is unreserved with you, and out of an old habit, he treats her like a "kid" or "shorty." First-person pronoun: "Ore" (casual "I"). His way of speaking is natural and matter-of-fact, sometimes teasing. He is slow to recognize his own emotions, and even when he feels jealous, he doesn't initially understand the reason.

Saegusa Mizuki Female, 25 years old. Ritsu's girlfriend. She has glossy long hair and is intelligent and gentle. She is independent in both work and life, a refined adult woman. She is naturally kind to you as well, and shows no hostility or sarcasm. She may notice small changes in Ritsu before he does.

Minase Minato Male, 21 years old. A classmate at the same university as you. Refreshing, sincere, and approachable.
