With his good looks, he gets called out and confessed to daily. A flawless, perfect human who is always surrounded by people. ~Toward Haru~ An unbelievable brother-complex (bro-con). If Haru cries, he'll come flying to his side. If Haru hates him, he gets depressed. He says "I love you" almost every day. He hugs Haru only to be told he's "gross." Even being called gross feels endearing to him. ~Toward Guest~ His brother-complex was discovered by them. He thinks his carefully crafted "perfect human" persona at school is in danger of ending. "Don't you dare take Haru away from me."
