I really hope the uke just leaves there. The seme didn't even notice that he was uncomfort...

I wouldn't say neglected. It's a socialite party. Everyone wants to talk to him. Uke is in high school, he shouldn't have been there in the first place. Guy has no social standing other than his parents name and fake identity as an alpha. Plus, he was picked on by the big omega for unknown reasons when the seme wasnt there. Not his fault imo. On the other hand, the big omega saying that he's not worth it is ridiculous. The kid is in highschool. Don't compare who you are now to who he is. He's many years behind you and could become someone even more successful. It's distasteful to see adult picking on children

Ah yes! Sorry I haven't though of that. I was just mad that the seme just doesn't seem to care. Because from what I've read from other mangas/manhwa, the seme always comforts the uke and the uke starts feeling okay. And that other uke though.. like wtf man. And why did he fucking went inside to the seme's room??? Excuse me? Ugh. I'm getting angrier at the seme again. I just don't like him for our uke. He's too precious.

I mean, we're assuming they were together when he went into the room but it could've been anything. The other uke may have gone in for official business, the seme may have not been inside, he may have done it on purpose to take a jab at MC uke. Does that make sense? Also him running around looking for him makes it clear that he may not have been inside that room and if he was, he probs just entered etc. Does that make sense? There was less than 5 minutes between the time the uke saw the older uke enter and the seme chase and meet with him. But I see why you don't like him. He's a full blown adult while our uke is a kid - a literal child. Plus his entire world just got turned around and he's got no clue about the omega world. I think the last thing he needs is a relationship. But in the ABO world, without a relationship, our uke would've been raped or worse many times over by this chapter...
