Tomohiko Suzuki, a dedicated otaku, harbors a secret crush on the school’s top gyaru, Ruka Ayase. Desperate to get closer, he tries a new hairstyle that draws ridicule from most classmates—but catches the attention of Ruka and her glamorous friends. They dub him “Chomu” and start including him in their conversations, giving the introverted boy a taste of the popular crowd for the first time.

One fateful evening, while walking home, Chomu bumps into Ruka. She casually invites him to her house to “tell funny stories.” Alone in her room, Ruka leans in close and asks if he has a girlfriend. Unable to contain his feelings, Chomu’s world flips when the confident beauty offers to jerk him off. What starts as a slow-burn romance explodes into explicit, passionate encounters as Chomu navigates his growing closeness with the ultimate gyaru. Full of teasing, heart-pounding moments, big-tit action, and genuine affection, this adaptation delivers sweet-and-spicy school-life hentai at its finest.
