Zero sympathy for Yoojoon, he shouldn't have rejected Jihyuk when he confessed. Maybe he didn't realize his true feelings at that point, but he was utterly cruel in his rejection. Not even a "Can I think about it?"
Can't stand Eunseong and his manipulative lying ass either. Jihyuk is too good for either of them, he should ditch them both.

I can't stand stories that can be resolved with one simple honest conversation between the characters. That's all it would take this resolve this mess. Plots build on a little poor communication are so flimsy, as weak AF. Before you come at me with, "If you don't like, don't read"; well, it started so good with an actual storyline and now it's just predicated on poor communication between two bumbling fools and one manipulative character.

I agree with Jaekyung rebuffing Dan, but not in the manner in which he did it. He was so cruel and brutal about it (which represents much of their relationship really).
By taking on side jobs and feeling tired all the time, I feel that Dan probably compromised his work as a physical therapist. Which is partly why Jaekyung feels so frustrated – he's paying top dollar for Dan to give this gig his very best. And it was all over a trinket (albeit an expensive one) that Jaekyung could easily buy himself.
Yes, it's the thought that count and Dan bought the present out of the sweetness of his heart, but I feel that Jaekyung always made his intentions and expectations of their working relationship clear from the get-go and is paying Dan the requested salary.
Anyway, from a romantic relationship viewpoint, Dan is much too good for Jaekyung.

Heesung was introduced to be a foil to Jaekyung. They are exact opposites.
Heesung seems like perfect boyfriend material – says the right things, buys the right gifts, showers Dan with sweet attention, but he's fickle, superficial, exploitative. If he won Dan over, he would happily ditch him with the next breath without another thought. His "love" seems unconditional (on the surface) but it's completely self-serving.
Jaekyung seems like a total asshole and seems to say and do all the wrong things – but he's the asshole who rescued Dan from loan sharks, paid his debt, gave him a place to live with no end date, visited his grandmother, paid her medical bills, doesn't seem like he'd ever turn Dan out onto the streets or ditch him any time soon, even if his jinx was resolved. Maybe their arrangement is exploitative and Jaekyung is forceful. But every time Dan expresses gratitude, Jaekyung pretends his kindness is 100% self-serving and I don't think that's totally the case. I think Jaekyung is now protective of Dan in his own way.

I can agree here but they're both assholes, youre right about Heesung 100% however lets be clear here, there are kind things Jaekyung has done but the way he treats people is pretty terrible. Hes clearly suffering severely from the sin of pride. Jaekyung probably is a sweet guy underneath all the layers, the issue here is that those layers are sexually abusive, violent and aggressive. Its all fiction but if we're being serious here Heesung and Jaekyung are polar opposites but equally pieces of shit. Theyre just on opposite sides of the spectrum. Heesung is shallow and manipulative and then Jaekyung is abusive and aggressive. Theyre both exploitative though, Heesung sucks the life out of people hes interested in and then leaves them high and dry and Jaekyung takes advantage the favours hes given Dan and uses it against him whenever he feels shitty. Giving him a ride to Heesungs house? Takes advantage of the situation and makes Dan use a sex toy in his hissy fit of jealousy. That sex contract he gave Dan? Inherently sexually exploitative. I dont this outright abusive behaviour is any better than someone who is secretly the devil. Maybe its easier to identify but that pretty much it.

I agree with Jack…. Mostly.
Jack could had when deeper with Jaekyung because he could had solidified that.
Toilet man. Jaekyung isn’t that abusive. That sex contact I think he thought was the way to get Dan. Man when you hate something you sure can make it sound worse.
Okay when I was in college. They had an experiment. They made a website saying how H2O is bad for you. The 2 is small. They explained how H20 would destroy things and so on. It was outlandish. I know people believed it. People wanted to get rid of it. But how do you get rid of something you need? How do you get rid of water? You need water. Yes too much water will harm/kill you. I couldn’t find a source.
Dan is a cup of water.
Jaekyung is a gallon of water.
You make him like him is a whole planet of water. Jaekyung waterworld to you. You give him too much power and allow him to live rent free in your head.

I think Heesung and Jaekyung are equally shitty people, i was nitpicking at Jaekyung here because the OP already made a point about Heesung that was valid. Believe it or not my dislike for Jaekyung has lessened and is more an equal balance between him and Heesung. My point was to say that just because Jaekyung is a different type of abuser doesnt mean hes any better. If the way ive been describing Jaekyung makes you think im exaggerating but the way i describe heesung (since you havent mentioned it) doesn't. You might just be biased, i mean i think the point i made was pretty neutral. Im not favouring either of them (not that you said that). Though, there isnt too much to say about heesung i mean hes been here for less than 10 chaps. I'll flame him once he does more things.
The OP only pointed out Jaekyungs good traits (mentioned his bad traits but didnt go into it) so i just wanted to set the record straight and say that just because hes done good things doesnt make him a better person. I mean if someone made the arguement that Heesung was better than Jaekyung because he treated Dan better after reading this chapter it would be pretty stupid.

No. I am not biased. I don’t have your view on either one. I like to see what Heesung does in the next chapter because I judge him that harshly. I leave room. I am open minded. Would you can the over dramatization of trying to make it look like I am being biased. Why do you bring in irrelevant information… I make a comment and did not explicitly mention JK actions because they should be known and I explained Heesung’s actions but I was biased. It is irrelevant to mention an already established character actions. This time I didn’t talk about Heesung and I am still biased. I explained then I am only sticking to the story. I am not biased. You are making points like I should had said something about it but it was irrelevant. They are not polar opposites. You would come up shorthand on the amount he has been violent and aggressive. He is mostly silent. The car ride are you sure you have an accurate pov? The sex contact are you sure? He is abusive. He could be worse. How people make the devil today, he is no where near the Devil. He is not evil. Saying that is clear a biased and dishonest. You were not being neutral. You act like he has murdered Dan’s family and have Dan confided or something.

In a previous chapter, Heesung's minder said that he's fickle and falls in and out of love and love bombs people, which is what he's doing to Dan. I think it's the thrill of the chase for him and he's able to abruptly move on from Dan. Potato sees right through him.
I'm not saying Dan's relationship with Jaekyung is healthy either. But I can't see Heesung taking the initiative to visit Dan's grandma (without turning it into a photo op anyway), rescuing Dan from the loan sharks, paying his debt and his grandmother's hospital bills. Jaekung says that having Dan live with him is not to help Dan but for selfish reasons, but regardless of his motives, he has a constancy about him that Heesung clearly lacks.

I understand your point that Heesung *might* not be the right guy for Dan. But I don't agree w you saying Hessung is trash. He hasn't done anything harmful to Dan in the story so far and he's doing his best to appeal to him in his own way (E.g., giving an excessive amount of gifts). That's already a huge point for me to prefer Heesung.
If we're going to nitpick Heesung's character and compatibility w Dan, then Jaekyung should certainly be the first person to criticize. If Heesung lacks the consistency, then Jaekyung lacks the empathy to sympathize w Dan. But the ML isn't rlly the main topic of this discussion. My two cents.
Ash started off being a helper to heal Lyle's aversion's sex. So Ash was a gentleman who romanced Lyle, showed restraint and also the normal positive aspects of a relationship. It was only meant to be a short-term arrangement so Ash could curate the parts he presented and also he genuinely wanted to be a good human being and help Lyle.
The other side of Ash's personality is one that is passionate, demanding and possessive. So kind, romantic, gentlemanly Ash is still Ash. And passionate, demanding and possessive Ash is still Ash. Lyle is just coming to terms with both sides, and Ash is coming to terms with the fact that both sides are still him and Lyle just saw one side initially.
Lyle was scared that Ash would get sick of him, so he was looking for his own apartment. Ash both helped but mostly hindered Lyle's apartment hunting, while secretly wanting Lyle to live with but being afraid of Lyle being able to cope with all of him. Lyle was the one who started off as vulnerable; now it's Ash learning to be vulnerable and 100% open to Ash.
