There is a doujin I have been looking for recently. Add something I read something like ten years ago. It starts out with a girl getting raped who shortly after jumps off the roof cause she found out they got her pregnant. Group of guys target another girl not caring either way, and they end up pissing off the girls, girlfriend? Either way this characyer ends up blowing up the main d-bags dick off at the end and he kills himself. What is this called?
