Chitose Is in the Ramune Bottle

Saku Chitose, known for his good grades and popularity, starts his second year of high school. However, his online reputation as a "Class 5's womanizing scumbag" doesn't seem to bother him. As he reconnects with old friends and meets new ones from the school's social elite, his homeroom teacher assigns him a task: convince Kenta Yamazaki, a shut-in classmate who harbors a strong dislike for Saku, to return to school. Saku visits Kenta's house to tackle this challenge.
