It affecting his way of thinking, remember when he thought that yohan was spying on him and he became paranoid and began jumping onto conclusions its one of the diagnosis of having a mental illness,
First I hate him too, cause I thought hes just making excuses to cheat and not be loyal, and the porn vid play a huge part to worsen his condition
Yeah he was talking about masturbating cuz it felt good but he was a kid too young to understand that that is private stuff. He told neighbour boi doing this felt good and his mom scolds him for doing that so he does it in secret. Then that hyung offered to "HELP HIM". One day he told hyung he has a crush and THEN hyung says " IT DOESN'T MATTER. U CAN'T STAY LOYAL. WHAT U HAVE IS AN ILLNESS. "
Well normally child would not feel any sexual desires at young age, and his neighbor tolerate it instead of correcting it, he tell that he has a mental illness, (I think it's just to make fun of him, not sure) and he take it seriously and as he age he is developing the mental illness, about the rape I'm not sure too, it's been awhile since I read some past chapters so my memory can't keep up
His illness is no joke, he could have a treatment when he was a child but no one was there for him to check him, the mental illness is very rare and my sis told me is it really possible to exist
