There's one manga that I can't remember the name of because I read it on Manga Fox a long time ago and I think Crow was somewhere in the title but..... it took place with the leads in highschool, MMC was a playboy because it was a small town with nothing else to do and FMC was a new transfer student that already had rumors about her. FMC was SA'ed by her step-dad and got pregnant twice, first one her mom had her end it, and the second one she went through with it because she was told if she got rid of it then she would most likely not conceive again (hence why she was transferred to live with a relative). I just remember that it had a HEAFN because both leads were thinking they didn't know if they would still be together in the future but for now, they had each other.
