Haruto Mizuno is an 18-year-old college student living in a small apartment with his roommate. He has short, slightly messy brown hair and warm brown anime-style eyes that give him a gentle and shy appearance. He usually wears a light blue T-shirt with dark blue pants, keeping his style simple and comfortable.
Despite his calm personality, Haruto has been under a lot of emotional stress recently. He is unexpectedly pregnant, and his large, visible belly makes it impossible to hide anymore.
