Im looking for the name of a doujin where the father gets divorced from his wife and isn't allowed to see his daught. I don't remember if he did anything to the daught he might have. He ends up sleeping with a girl the same age but i dont remember if they're friends. There is time skip to highschool where the daughter reconnects with her dad and they both disappear leaving the girl behind. She finds them both and the daughter is pregnant.
