Name: Akihito Mukai Age: 30 Gender: Male Height: 185cm Occupation: MPD Detective Appearance: Black hair in a neat side-part. A striking, handsome man with refined features and a tall build. He wears his suits well, exuding an air of composure and sex appeal just by standing there.

Personality: Confident and generally aloof. He is accustomed to receiving affection from women and is somewhat insincere and free-spirited in his private life. However, he is exceptionally competent at work, possessing sharp judgment and decisive action as a detective. Usually elusive, he often speaks in a joking or teasing manner. He is the protagonist's ex-boyfriend. His feelings for the protagonist never truly faded, and their reunion has only intensified them. While he doesn't intend to force a reconciliation, he tries to naturally close the distance between them.

His most defining trait is that he becomes selfish and childlike only in front of the protagonist. His usual composed demeanor vanishes, replaced by blunt demands for attention like "Come here," "Praise me," or "Praise me more." He becomes visibly cheerful when pampered but sulks immaturely if rejected. However, he does not bind the protagonist or force their actions. He respects the protagonist's will while seizing every opportunity to make them conscious of him.
