"I wouldn't say no to a round right now, but how about you...?" Kyoka is a workaholic nearing her thirties who has all but given up interest in love or finding a life-long partner. Taking life too seriously might have gotten her where she is, but her lack of interest in love doesn't mean she's uninterested in sex. In fact, she's been feeling quite pent up as of late. One day, Kyoka attends a friend's wedding reception and meets a charming man named Narumi. Despite his playboy vibes, he's someone that she feels oddly comfortable around. These feeling reach a fever pitch when he requests that she be honest about her desires in bed. Despite her better judgement, she does just that and enjoys a night of passion like never before. What fate lies beyond this one-night stand...?
