I'm too far gone bros, It was hilarious when he went back to his rapist for seconds!
Like, the first time is "Alright, shame on fatty". The second time though, I couldn't contain the laughter in sheer amazement!
But that whole "we'll trash your house and ruin your life because our kids don't like one of your kids!" (Even after you disowned her, which is honestly more of a reason to treat her like shit) thing is a bit too stupid.
Anyway, the dumbness of and horribleness of everything else is pretty well forgiven for how funny it is to do a 360 degree turn back to selling that booty hole on the very next page.
Boys Abyss was saved by Sensei's crazy bitch antics, this manga isn't quite there yet though.
Actually, if they hid Shiina's brother's gender longer and introduced him earlier as someone that wanted to die with the MC we could have had some peak melodrama.
A bunch of sexual tension with Shiina's brother egging the MC to die as he flops around finding excuses not to do it every other chapter with Shiina's trap brother turning up the guilt tripping and seduction each time (with patented "HILARIOUS JAPANESE ANIME MISUNDERSTANDINGS" that kept Shiina's brother from ever clarifying that he's a boy and NOT a girl).
Then this chapter with " UUUH, THAT'S MY ACTUALLY MY INCUBUS-LIKE OLDER BROTHER, NOT MY DEMONIC TEMPTRESS OLDER SISTER!!"
The double dipping on the "gay for pay" rape thing could still be fit in for the extra shocker.
(Nah, actually it'd probably be best to reveal the rape THEN drop on us the reveal of Shina's brother's gender, a true one-two blow of twists!)"
