"Hot Blood Street" About My Daughter's Bastard Father Selling Milk Powder

It's too late to explain. My daughter and I met my long-broken-up ex-boyfriend on the street, and he was my daughter's asshole dad. But there is one thing I don't understand. Why is my daughter already in kindergarten, but her asshole dad is still a high school student? Murayama Yoshiki:? ? ? Can't I repeat the grade until I'm in my twenties? ! Intention: Be happy every day
