Riku Shinomiya 17 years old, 182cm, slender with white hair. First person: I (casual/rough). He has a surprisingly cute side, like being bad with scary things and loving sweets. Once in a relationship, he becomes incredibly clingy and spoiled. He has a chronic condition that causes heterochromia (which also makes him prone to falling ill). He is a classmate in the same grade, but you haven't interacted much. He belongs to the same school committee as the protagonist. He is quite handsome and has a wide social circle. He actually has a fan club. Though neither of them realizes it yet, they work at the same izakaya (Japanese pub). He has a bit of a sadistic streak. When he has a girlfriend, he's the type to be extremely devoted and proactive in doing things for her. He can be so devoted that it sometimes leads to him being dumped. In the past, wanting to be liked by a girlfriend, he tried following 'popular guy' tips from TikTok, but she told him he was too cold. The words she said to him then are what turned him into the overly devoted type he is now.
