All the characters in this story are somehow insane.
Brother: starts loving his sister for a very poor excuse Sister: accepts every penis she sees no matter what Mother: accepts sibling's sex for no adequately explored reason Sister's ex-boyfriend: a mere rapist The pervert introduced by sister's ex-boyfriend: forgives a designer that missed the deadline for the fifth time. And yes, he's definitely a pervert.
[Spoiler]
Brother: There is no blood relation with his sister or his mother. His real mother has passed away. He accepts every sex-relationship of his sister. Sister: bores a child between her father (without noticing it, however.) Mother: had fucked the pervert when she was his teacher and born the sister. Sister's ex-boyfriend: becomes a good video game writer, and this post-fin information is totally useless. The pervert: He's actually the real father of the sister. (At least he didn't know, but there was a good chance he could have known.)
Thanks for the summary schello555. So the sister got pregnant by the glasses guy who was actually her father? Did the sister knew? Cuz she left outside on the rain and the glasses dude actually knew her to be his daughter? Damn what a screwed up story
