Tsuchida is starting his first day as a kindergarten teacher. On his way to Hanamaru Kindergarten he runs into a little girl named Anzu who is alone waiting for her mom. When Tsuchida asks her where her mom is she accuses him of hitting on her. Having enough trouble fitting in as the only male kindergarten teacher, Anzu outs him at the opening ceremony and expresses her love of Tsuchida who has just been assigned as her teacher. Anzu will now do everything within her power of making Tsuchida's her, even if it means getting in the way of Tsuchida's feelings for his co-worker Yamamoto.
