Nagisa is an incredible beautiful kindergarten teacher. Despite her popularity with men, she has always felt uncomfortable around men and has difficulty trusting them. This situation stems from the fact that up until college she had only attended girls' schools and in college her crush ended badly. One day she is taken to a marriage interview bar by her friend Isobe. Isobe signs Nagisa up to meet Fuguno for fun. She finds she shares a lack of experience with honest, unconfident, and goofy Fuguno. Thus begins the stray path she travels with him.
