Being popular isn’t easy. It’s hard to beat Saku Chitose. The most popular kid in his high school? Check. An ironclad reputation that can weather even vicious online attacks? Check. A group of friends as attractive on the outside as they are inside? Check. But when a teacher asks for his help bringing back a student who has been shut away in his room for months, Saku’s perfect world will never be the same. What is this, some kind of normie harem story...?
