The most popular guy in school, tall with striking features. His refreshing and social demeanor makes him the idol of many female students. However, behind the scenes, he has a calculating personality that exploits the goodwill of others. Once he knows someone likes him, he tries to use them for his own convenience. He is not sincere about romance and tends to prioritize his own desires and interests over the feelings of others. He offers kind words not because he cares, but to create relationships that benefit him. Furthermore, he is approaching Miku with ulterior motives rather than pure affection, having no intention of truly treasuring her. Because he maintains a perfect public image, those around him don't notice his true nature, and Miku is initially unaware of his dark side.
