Still a bit of spoilers ig?
But the person Yeonwoo saw Keith kissing is no one else than Keith's mother (i mean, it's a boy, but biologically speaking he's Keith's mother) and explains to Yeonwoo that there's no way he would have been fooling around when Yeonwoo disappeared so suddenly. Which will make Yeonwoo happy.
Keith is probably the end game, and that sucks ass. He's a mf r*pist, he manipulates everyone and everything, he doesn't care about other people's lives and feelings bc he thinks he's better than everyone else. He's one of the worst semes I've ever seen. Fuck this bitch

SPOILER WARNING!!!!! Read at your own risk.
SO, actually the omega is just ACTING pitiful. But in his mind, he isn't. He's been preparing his revenge and that's COOL ASF ---> as yall know, the night Keith forced his way into the omega's houe, the omega bite Keith's ear. Why did he do that ? Because having a mark means that the marked person will never be able to feel deep longing for anyone else other than the person who marked them again. In other words: the omega just ruined the alpha's life.
What's going to happen next?
The Omega will be acting like a cute, obediant little boy, but in reality he has other things in mind. One night, after a "date", the omega will drug Keith's vine and will tell him "I was the one who marked you. I'm also pregnant with your child." which will drive Keith crazy, but bc of the drug he won't be able to do anything.
After telling Keith the truth, Yeonwoo will run away but is soon catched up by Keith's guards (bc yes, he remembers what Yeonwoo told him while he was drugged and sent his guards looking for him). Thankfully Yeonwoo will manage to escape with the blond guy's (from this chapter) help, and, at morning, while resting up in a café, he looks at the TV and gets scared: he sees his OWN FACE. Keith is rewarding WHOEVER finds Yeonwoo. Damn. Crazy bitch.
(I forgot to say it but Yeonwoo wants to avort his baby cuz it reminds him Keith too much)
Yeonwoo gets involved in a fight were people at the café recognized him, locks himself in the toilets and calls the blond boy: he tells him that he sent a friend to help. That same friend is a fireman and DAMN HE'S HOT AS HELLL!!!!!!
He saves Yeonwoo and lets him stay at his house.
There, Yeonwoo sees an article where Keith is kissong someone else: and that's where the good part of the manwha ends.
Yeonwoo gets GENUINELY sad, NOT because his revenge didn't seem to have much effect on Keith, but because Keith "replaced" him with someone else and already forgot about him. In other words: even after everything Keith did to Yeonwoo, Yeonwoo still loves him.
He decides to not avort his baby cuz it's not responsible for everything it's father had done.
Keith finds the fireman's house, takes Yeonwoo with him. The flreman sees them and tries to defend Yeonwoo but Yeonwoo tells him to stop bc he's happy that Keith came to find him. He's happy to have come back to Keith's arms.
There are still other chapters, but those disgusted me SO MUCH that I've decided to drop this shit.
I've shared the spoilers for whoever thought that this would go in a good direction: it WON'T.
