Did Seungho ask Nakyum to paint that moment between them? Or he didn’t ask and when he saw the painting got delusional thinking Nakyum liked/had the hots for him and that’s why he went for it and got surprised and angry at Nemyum’s rejection?
Or did he ask for the painting and when he saw it got super horny anyway and tied Nakyum up because... he knew Nakyum would try to escape because he doesn’t like him? Why does he seem so surprised then at whatever Nakyum tearfully says to him? Maybe because he thought all this time Nakyum remembered the sex between them and was surprised and angry that not only Nakyum didn’t remember before, but when he did was so disgusted he hit Seungho?
Or did Seungho think that he’d make Nakyum remember and somehow he’d be accepted anyway because he’s crazily entitled? Or did he always perceive Nakyum’s dislike and expected to be rejected, and was only surprised due to being hit?
Sooo curious to know what Nakyum tearfully said to him. Whatever it was, really hit something in Seungho by his expression. I think it’s the first time I’ve seen he so surprised and upset at something. We’ve seen his cold angry face before, when he seems to laugh a lot of times or show a psychotic expression. His face at the panel after whatever Nakyum says angry and in tears is the most... hurt, I guess, I’ve ever seen him.

For those curious, according to the Chinese translation
Spoiler:
Nakyum remembered what happened that night and said that he though it was the teacher and not Seungho

I did my own Korean translation. na-Kyum says that those words-' I like you' or 'I want you' is meant for In-jun, not for Seungho. It was like Na-Kyum gave him another blow after punching Seungho's face.
Our egoistical lord got pissed and smashed our poor baby's face to the ground.

Things I can think of happening as soon as Nakyun wakes up from the events of chapter 21, if he really passed out after sex:
(completely disregarding here the new chapter 22 raw that I didn’t understand much about)
A) Nakyun doesn’t remember anything from last night and goes on thinking he’s still a virgin and everything was “just a dream”. Even if Seungho cleaned him up, I think this one would be hard to happen seeing that Nakyun would be feeling some obvious discomfort down there and would know something was wrong. Still might be possible if he’s in strong denial.
B) Nakyun really thinks he slept with his teacher and goes happily see him. The teacher would break the truth to Nakyun in a disgusted and angry way.
C) Nakyun knows he slept with Sangho and feels so sad and ashamed he decides to run away or tries to commit suicide.
D) Nakyun knows he slept with Sangho and Sangho uses that to prevent him from running away or doing anything rash, with the treat of telling the teacher everything they did and what Nakyun said. I think that’s the most probable one, and it can also be something that happens after option A (it’d be something like: Nakyun thinks it was a dream and is in denial but Sangho breaks the truth to him and threatens him).

I can't buy that he doesn't know something happened down there. Unless he thinks sex dreams get that vivid or he woke up and was like, "Hm... it feels like an eggplant was shoved up there. Odd."
It looks like he believes it was the teacher, but thinks the teacher is angry at him now for "seducing" the teacher.

If someone kept behaving the way Hyesung does in the real world, I’m sure the marriage wouldn't last. He never communicates his feelings and is always treating his husband unkindly, never expresses how he misses or loves him as well, never show he’s thankful or does any romantic gestures.
“So he has traumas”, but that does not justify not trying to do any better. Relationships are something that takes effort on both parts to work, and Hyesung never does any of that!
If this story was in the real word:
1) Hyesung would sadly but definitely be cheated on.
2) Dojin would not cheat but would finish the marriage.
What’s probably going to happen in the story:
Dojin will not cheat, Hyesung will misunderstand anyway (probably with the new alpha character) and have a dramatic diva drama moment — lashing out as Dojin as always — regret mistreating Dojin, getting back together and the grand finale: Dojin happily spending eternity being Hyesung’s loyal puppy that would never cheat, doing everything for him and never receiving anything back, maybe sporadic moments of obvious attention and love.

To be fair Dojin basically raped Hyesung before and in this chapter again. Being married doesn't mean, that you can fuck your spouse, when they say no.
This author has a thing for toxic relationships and non-con, but unlike in their other work, there is no character development and the pair is just going in circles. And sure Hyesung can be very annoying, but his world crumbled, suddenly realizing he is an omega and getting pregnant. Dojin, while being better choice than most, is no saint either. He might try to protect Hyesung and shower him with affection, but never stops to think about, whether his affection is wanted.

I mean, you can't really blame Hye-Sung for having problems to express his feelings. Their relationship was "rushed" at the beginning, usually you learn to know each other first and it's a step-by-step process. Here, they just started a relationship because they were into it, now, even if they are married and have a child they didn't really have time to do all the steps. Thes thigns take time and they just need to go through it.

I agree. Marriage is supposed to be a two way street type of thing. It’s supposed to be an agreement and trust on both ends. Tbh it’s really annoying seeing Hyesung act so cruel to Dojin. But it’s also wrong what Dojin did to Hyesung. Like fr both of them need o grow up and stop acting mature cause it’ll just be a viscous cycle between both of them. Hyesung is an omega he needs to accept that and move on with his life. Dojin needs to stop being so forceful and automatically goto sex. Like fr if this was real life they would be divorced by now. They both need to grow up.

I love Taku, but he definitely made a suspicious face right after he sucked on Haesoo’s neck... And just when Haesoo was thinking “Should I trust him...?” I think that’s definitely foreshadowing for something. I believe it’ll all turn okay in the end, but I’m totally expecting some twists from Taku.

I wish some friend of sensei's high school days would show up and we'd just have someone to ship him with <3 Not really into Sensei x black haired girl student

The manga can be realistic and still introduce a more compelling love interest for the teacher, one thing doesn’t have to cancel the other. The possibility of an old high school friend was just a fun example, but as a sucker for romance, I’d already be happy if the teacher found a cool love interest, no matter how haha
If he doesn’t though I’ll just have to be satisfied with shipping the guy that created a fake profile and his cute friend Hopefully there’s a sequel for these two haha
Now I want the manager's history so bad!!!! A spin off with him and his playboy ex band mate would be AWESOME
