Why the uke so stupid?

He's like a fucking pushover
He himself is a victim back then and he couldn't finish his highschool or go to college
He's covering his parents debt while working multiple jobs as a normal beta and they just have come and fuck up his life and they treat him like shit
Now he's a omega who can't even control his pheromones and can't function normally
He's a saint for not wanting to kill their fucking family and bratty asshole ML
