Man 3

About

Appears in Koukai no Umi (Sea of Regret) and Suimenka (Behind Closed Doors). He is friends with 1 and 2. One day before their middle school graduation, he shows 1 some gay AVs and claims that he finds gay people gross. After 2 gets rejected by 1 at their middle school graduation, 3 confesses to him and they begin dating.

In Suimenka, it is revealed that he has loved 2 for a long time, and showed 1 the gay AVs to discourage him from answering 2's confession. He gets jealous very easily and is possessive of 2, suspecting that he still has feelings for 1.
