Sangwoo is being unlikable rn is most likely because he's super drunk rn. Not only he rarely gets drunk, he's in a total pressuring situation. He can't think rationally rn. Just a drunk ass lover being emotional and pushing all the buttons. I hope Jaeyoung bares with him this moment. I hope Jaeyoung be like "OFC ! I DON'T WANNA SHARE U WITH ANYBODY ELSE. NOW TELL ME, DO U LOVE ME?!"
Here is what I think the future holds for them :
Uke tell seme they're not dating. Seme get heartbroken and doesn't want to meet uke anymore. After a month, uke gets frustrated because he haven't met seme in a long time and he couldn't get it up with anyone else. Uke reconciled with seme, then some drama scene. They end up together in the end. The end
No doubt he's experiencing gay panic in the middle of the night and probably can't sleep.
