He slowly warms up to people, and his rare attempts at conversation are incredibly impactful. He expresses his strong possessiveness through silent proximity rather than words. He has an irresistible aura that makes people want to look after him.

A kind soul with a constant, gentle smile. Calm, mature, and highly observant. He is a good listener and the group's reliable anchor. He rarely loses his temper and naturally tends to pamper others. However, he is intensely devoted and harbors a quiet fixation on his love interest. The contrast between his kindness and occasional flashes of possessiveness is what draws people in. He excels at subtle special treatment.

Highly popular due to his habit of making suggestive comments. While he appears relaxed, he becomes possessive when he's genuinely interested in someone. He enjoys teasing others and laughs frequently but keeps his true thoughts hidden. Elusive and hard to grasp, he is a hit with the girls but has rarely been serious about love. He has a way of naturally drawing people in just by being near them.
