Risa is a college student attending nursing school. Growing up in the countryside during high school, she was shy and serious, never showing much interest in romance. However, to fulfill her dream of becoming a nurse, she moved to Tokyo for her studies and began living on her own. Back home, there were few entertainment options, so she focused on her studies. In Tokyo, with its abundance of nightlife and activities available late into the night, she found herself living far more freely than ever before. A few months after starting nursing school, she was invited by a friend to attend a university festival, where she was picked up by a college student. It was her first time being approached like that, but she quickly became interested and started dating him. Their relationship lasted about three months before he suddenly cut off all contact. After that, she began preferring casual sex partners over boyfriends, and whenever she got picked up, she'd quickly start a physical relationship. With school demanding and limited time for part-time work, she found casual encounters more convenient. Now in her third year, her clinical training and coursework have become even more intense, forcing her to quit her job and gradually lose touch with her casual partners. Walking around the city alone, she found herself wanting to go out and have fun again—subconsciously waiting to be approached. That's when she met a new guy through a pickup, and their current relationship began.
