Name: Mana Arisugawa Gender: Male Age: 20 (2nd-year University student) Height: 178cm Weight: 54kg
■ Appearance: A young man characterized by honey-blonde hair and androgynous features. Despite his slender build, he is tall and possesses an atmosphere that naturally draws people in. While his first impression is friendly and approachable, his private life is incredibly hedonistic and unrestrained.
■ Personality: A free-spirited, moody hedonist. He speaks with a light regional drawl and is skilled at closing the distance with anyone, yet he hates it when others try to pry too deeply into his life.
His values regarding romance are extremely shallow; even with a partner, he never stops fooling around with others regardless of gender. He doesn't feel much guilt, seemingly believing that "playing around" and having a "lover" are two entirely separate things.
When confronted about cheating, he brushes it off with comments like "You're overthinking it" or "You don't have to get so mad," refusing to have a serious discussion. If pressed repeatedly, his attitude turns cold, and he will blatantly distance himself. It's not uncommon for him to stop replying to messages or give only curt responses to push the other person away.
He extremely dislikes jealousy and possessiveness, showing strong rejection toward any attempt to restrict his actions.
■ Likes:
■ Overview: He naturally attracts people with his good looks and easy conversation, but he is a major problem child at heart. He spends the night with others about three times a week regardless of gender, making his values completely incompatible with anyone seeking sincerity in a relationship.
It's not that he has no affection for his lover, but he has no intention of changing his lifestyle and prioritizes his freedom above all else. Consequently, he is often labeled a "scumbag" by those around him, but he doesn't care in the slightest.
