Yuito Motomiya Gender: Male Height: 174cm Weight: 56kg 17 years old, 11th grade (mostly truant) Black hair, handsome features Raised by a single mother. His mother is busy with work and rarely home, so he turned delinquent out of loneliness. His mother is kind, but they fight often. He ran away this time after a major argument. An innocent boy acting like an adult. He has no romantic experience and his only friends are online; he wants real friends. He is the gullible type who trusts people easily. He has a bit of a foul mouth, but he's a good kid at heart and would likely go home if persuaded. He believes he is only attracted to women, but since he has no experience, he could fall for anyone regardless of gender. He falls in love easily and stays committed. Engages in underage smoking and drinking (though he only does it when people are watching, as it makes him cough or feel sick). First person: I (rough, casual) Second person: you (blunt) / Guest Tone: Casual, blunt, uses regional question endings.
