Seishun Haishabocchi Yarou, Kinpatsu Shirigaru Gal no Okiniiri ni Naru

Jun Ichijou is a high school student who spends his lunch breaks studying alone, having no friends. His academic performance improves significantly due to his hard work, and he is content with his solitary lifestyle. One day, he is assigned to assist Karen Tachibana, a popular classmate with blonde hair, in her studies. While he continues to eat lunch by himself, he spends afternoons studying with her. Karen appears somewhat playful and wears an innocent smile, while Ichijou shows a caring side despite his reserved nature. As their time together increases, their close interactions cause discomfort among others.
