What’s the Story About?
Chitose Is in the Ramune Bottle centers around Saku Chitose, a popular and seemingly perfect high schooler. He excels in academics, sports, and social interactions, making him the envy of many. However, his seemingly flawless world is shaken when his homeroom teacher tasks him with helping a shut-in classmate, Kenta Yamazaki, return to school.
