Why is this rated so highly

I was really loving this story until caesar shot lee-won 4 times and then proceeded to rape him for a fucking week without break. Seriously how was he even forgiven, lee-won has some crazy stockholm syndrome because how can you even love him after all of that. The only reason I finished this was because I was waiting to see if caesar even gave an apology for all the shit he did but oh wow why am I surprised there’s no apology! This could’ve been really good but why was the only way caesar thought of subduing lee-won so he wouldn’t leave is by shooting him? He is well aware how strong he is and he could have easily knocked him out or dragged him back himself without harming him. And before any of you defend him by saying he doesn’t know that you shouldn’t hurt what you love, he quite literally protected lee-won from the sniper and took a bullet for him because he didn’t want anything to happen to him, but it doesn’t make any sense how he inflicts that very pain onto lee-won and doesn’t bat an eye.
