I've been searching for a specific H doujinshi that I read a while back. Synopsis of the story is something like:
Guy and girl were childhood friends that became estranged. I think the girl just doesnt like him over time and eventually bully him or something. Then one day the girl got into an accident and pretty much became a vegetable. Her parents became distraught over this but cheered up after the guy volunteered to become her caretaker. It was normal at first but eventually he laid hands on her and lewd shit happened that ended up with him asking her parents for her hand. They agreed and then she eventually became pregnant. Some years later her mind recovered only to find out about her current state and she just kinda mindbroken/resigned to it because her body has been conditioned.
Does that ring any bells?
I did put this under bounty/request last month but there were no replies so I figure I might try again here.
