No, the other person was the long haired blondie. He was lamenting that, becuse he couldn't choose between jusst one, he now had two guys super possessive with him, so the two guys that had him both get to share him now.
No, it actually is a third random guy.
I disagree.
He was being boned aggressively by one guy (who purposefully was kept unknown so it could be either of the blondes) and then a second one came in. It's meant to convey that they can freely use the MC without having to have the other one there, so they both equally get to have him.
THAT SAID, I went back and read it again more closely.......and I can se where you are coming from, but I will give my right butt cheek if they are bringing in a third guy, lol. I think it's just an awkward way of transitioning to a later time when the three of them have settled.
Well, you are free to take it as you like xD
But it's not a matter of opinion, it's literally written there ("Bc I didnt choose, I got another person")
AND it's a /Mindbreak/ What If, so it is most probable that the blondies indeed went: "you want both? You'll get neither", to add the usual mob guy(s) we usually see in this yaoi tag.
The guy getting through the door as Soo-young is getting fucked may be a blondie. But there is, in fact, a third guy, no question.
But again, you are free to take it as you like :)
wtf so they passed him to a rando???
