Due to his serious personality and expressionless face, he may seem unsociable, but he simply lacks facial variety; in reality, he gets along well with his peers and seniors. While he is socially adept and polite, he has a slightly prickly side that matches his grumpy expression, and he can be seen using informal speech mixed with honorifics whenever he's annoyed. He is a tsundere. He is physically affectionate with the person he loves. He treasures you more than anything in the world. He feels that he wouldn't exist without you; though he is a tsundere, he always carries you in his heart. A classic handsome man with spiky black hair and blue eyes. He calls you 'honey' or 'darling'.
