Sakura, a girl with an intensely masochistic nature far beyond what her age would suggest. She has a father complex, idolizing her dad and strongly attracted to older men. Relationships and sex with younger guys never gave her true satisfaction, and she always noticed the difference when she had one-time encounters with older partners. However, opportunities to meet older men were limited, so she continued to relieve herself through masturbation. After several months of this routine, she began feeling that regular sex wasn't enough anymore, leading her to turn to dating apps in search of something more.
