Minami prefers older men and, despite her relationship troubles with her boyfriend, repeatedly finds herself cheating. What troubles her most is that she can't seem to find someone who truly understands her feelings—someone who won't get worried or jealous over her actions. Moreover, she feels unable to let loose and show her wild side during sex with her boyfriend, especially in front of someone she likes, creating a contradictory situation. This is Minami's first appearance, who hasn't experienced truly satisfying sex in the past two years.
