I'm gonna be hated but I don't give a flying fuck: I didn't like the first couple.
Not because of the "dynamic" everyone mentions in the comments but because it wasn't funny at all. I had great expectations but it didn't even make me smile, the second couple did a little bit at least... So yeah, I don't know. I think it could have been way better than this, in the end it was just boring. Maybe because it went too fast, everything was too obvious and the rare tentatives of humor were... Meh.
Sorry guys, this is just how [[ I ]] feel, it's good if you enjoyed it, but I didn't.

Alright Sunwoo is an angel and Hyunjin is a piece of shit. I hate him. And not even in a good way, like I would hate a very well written character, I just find everything about him despicable.
It was a nice story though.

Oh I get what you mean, but he still chooses the worst reactions possible. The man he loves lives with a little brother and never acted suspiciously. The little brother having feelings doesn't mean they will be reciprocated, have faith in your lover for fuck's sake... And Sunwoo never did a single shit that could have been misinterpreted, and didn't even intend to confess just to keep his brother safe.
Hyunjin selfishly assumed imaginary shits on his own and acted like a piece of crap without giving anyone any chance to prove him wrong.
Actually what I really hate is the absence of development in his attitude. He was detestable from beginning to the end.

I think there was some progress, kinda, in the sense that he became more up front about his emotions. It’s hinted that he’d even started to think about marriage and stuff too so I think the author wants us to assume that he’s finally letting himself love the uke. Plus sunwoo did do things in front of hyunjin that made him react so it wasn’t just one sided aggression! I just think you’re being too harsh, all the characters have their flaws after all.

What did Sunwoo do?
I must have missed something because I didn't see anything tho? The only "thing" from Sunwoo was him being all flustered after touching his brother to wake him up, his wild fantasy and of course when he indulged on acting a bit spoiled, but this was at the very end...
Even when he answered the phone call, he did it not wake him up (even if he was troubled by that invasive lover, he never went against him) and all along the story, he has known his place as a brother and Hyunjin's as a boyfriend, he never stepped out of boundaries...
WHAT THE ∆×□❍ ?!?!?
