After that unusual encounter, his life takes a turn when a new student named Momota joins his class and it turns out she is the same woman from the park. Momota confesses that their encounter was an attempt to boost her self-esteem due to the teasing she was receiving because of her height. As they grow closer emotionally and physically, they go on their first date to a planetarium, where Momota reveals her perverted side and enjoys exhibitionism.
