Yes, yes and yes to everything you said. I kept nodding my head and mentally applauding you throughout it all. Great insight on the two main characters and their relationship with each other as well as themselves. It also makes me sad to think that Seungho is able to show his (positive) emotions towards Nakyum only through sex.
I'm thirsty (like a fujoshi lost in a dessert) for that too and really hope it'll happen one day. He has to grow as a person so much though as well as to learn to understand and process his feelings (and others') in a more healthy way, so I'd say it's still a long way away. Luckily character development is one the things I live for, so this should be an enjoyable journey.
It's also nice to have people like you with whom I can have a conversation about all this. Thank you for that.
Yes I so agree with you. I think we are seeing him grow a bit. Like he is still mean about it but he decided he wanted Nakyum to feel pleasure when he saw him crying. There's also that panel where he is looking at Nakyum's cum on his hand and it's almost like he is confirming / congratulating himself... lmfao.
It is nice to have people to talk to without the conversation becoming a moral dick measuring contest. I really want to see Nakyum happy and healthy, but damn this plot is riveting in its fucked up-ness... (๑•ㅂ•)و✧

I doubt Seung Ho's family's power is actually dwindling. Notice how anyone who calls out that point has a bone to pick but other than that they still fuck with him? That means that he's powerful and the only ammunition they have against him is the issue that happened in the past with his family.
For those saying it's as if Seung Ho can't accept that he's not a romantic interest -- of course. Yes. That's exactly what it is. For the first time, he is interested in someone and like really interested in something more than their body and that person likes some fucking power hungry moron. It's vexing. His behavior is still dumb and bad, but his feelings are not unintelligible.
Seung Ho considers himself a man of some discernment and that is why he is interested in Nakyum. He has noticed there is something special about the way that Nakyum expresses sexuality. And that thing that attracts Seung Ho is not innocence--something closer to sensuality or depth of expression. It's something he craves for and so his literal motivation is making that thing his.
He is not concerned with destroying that thing. If he were able to destroy it so easily it would be worth much less, and if he did manage to destroy it, than Nakyum would be worthless. That's just the type of man Seung Ho is.
Now as for spoilers on why he insists on mirror sex where Nakyum can see them both AND feel pleasure is because he is hung up on their first time. He doesn't deserve to be but he's hurt by it too. He felt something real for the first time and the person he felt it with didn't even want him as a partner and the next time he tried to do it he couldn't produce pleasure (because Nakyum felt good because he thought he was with his sir). So Seung Ho knows what he did was wrong but is at the same time more fixated on the things that hurt him -- Nakyum's denial of his partner and of his pleasure.
Also he's super fucked up god as far as personal reactions go, I really wish he hadn't done this a 3rd time. I'm tired.
Also, a minor detail but, Nakyum's face in that last scene before Seung Ho grabs him again is one of a bit of confusion. Like he is learning to or has learned to like the sex, but the sadness is directly opposing any pleasure he may have felt. Learned Sir just hurt him, but Seung Ho at least provided some physical pleasure -- which is a powerful thing when you're feeling broken. Poor baby, he's an emotional creature caught between two emotional black holes.
