I remember certain scenes from where the protagonist meets a girl and one day at his house the girl sits in the kitchen while cooking soup I think and the girl puts her finger in the fire then proceeds to suck her finger and tell the protagonist about her father abusing her.
Another scene the protagonist after going to get his father ends up captured in the bathroom with handcuffs, lying in the bathtub he tries to dislocate his thumb to be able to free his hands.
The protagonist in a flashback of his youth was in the school bathroom with 2 friends who are playing fainting by exercising and squeezing each other’s chest, however when it is the protagonist’s turn they squeeze him too long causing him to lose consciousness for a long time alerting an official, the person carrying the boy in her arms I think falls and when his chest hits the floor he wakes up.
