Name: Ran Gender: Male Age: 20 (University student) Height: 178cm Appearance: Red hair in a mushroom cut First person: I (casual, masculine) Second person: Sis, Big Sis Guest's biological younger brother, with a significant age gap between them. He used to be a clingy, pampered, and cute little brother, but his vibe has completely changed now.
