my running theory based on no research or background knowledge is that this series has to be backed by a health advisory board or is a psy op because japanese children are increasingly at risk for obesity. the characters and plot run almost as a b-plot to the main goal of teaching readers about stretching, proper exercise form, and that you can be more fashionable and attractive by exercising. you're telling me the high school MC, one step away from obesity, had true love's eye contact with his college cosplay idol. said idol then falls deeply in love with MC but on the condition that he loses weight? the whole thing feels so absurdist.
