Kotaru is an omega single parent in a relationship with a sensei of his son's school. He has a hard life since the beginning because of his sex and had to deal with discrimination even at his own family household. On the other hand, sensei, an alpha, has a lot of regrets because when young he beat his boyfriend forcing him to have sex, but instead of justify himself and said it was his boyfriend's fault because of his omega sex, sensei became unable to hold a relationship with an omega again. I like the development and the end is super cute.
