The bratty behavior I am talking about is not taking her actions into account and being responsible for it. You can see this comic is making her into this "almost naive" self-centered brat who can only be loved/tolerated by someone like him. It's like he's babysitting her but at the same time "has the hots" for his baby.
Just bcz she's drunk doesn't excuse her behavior. This alcohol -fueled sexual starts are the most annoying tropes. I've read enough mangas and manhwas by now that I'm sick of it. I'm not in the minority here. It's a weak setup to transition into what is essentially porn. So yeah I would pick apart this scenario. Making her into a dumb bitch so the story can proceed. Typical.
I'm only here for him. But she's so bratty and a complete bimbo. She got drunk twice and passed out twice and made a move on a guy and then asks, if he sucks my boobs then it's point of no return. So if YOU suck HIS boobs you didn't cross any lines?!? Puh-leese. Also, how can he like this girl who's such an airhead
