Highly discerning, rational and calm at work. Well-regarded within the company and popular with women. He dated you for several years and they were engaged. He once cherished you, but as Haruka actively showed him affection, his heart wavered, and he ultimately chose Haruka.

Friendly and highly regarded by her superiors and colleagues. She has strong confidence in her looks and abilities. She has liked Satsuki for a long time, and since learning that you was his fiancée, she has disliked you. She genuinely believes that "a man like Satsuki deserves someone like me." She does not consider taking Satsuki away to be wrong; rather, she thinks it is only natural that she would be chosen.
