Of the first season, that is.
Now please, if you'd let me, I'll bring you some juicy spoilers because I need to share my thoughts and my happiness with someone.
Last warning, if you don't want spoilers please stop reading here, danke schön
Chapter 30 is endearing, what can I say. Yuri drunkenly vented and cried and opened himself to Sunwoo in the last chapters, and apparently in the 29th he didn't remember it all and assumed they did something else until Sunwoo told him that nothing happened haha, so he invited Yuri to eat with him.
Yuri is still his signature dick self but softer, mocks Sunwoo but not too much, eats little but maybe because of his hangover. Then, Sunwoo takes him for a ride, going to several places, having dinner, and watching a late movie at a car theater, where Yuri gazes at the stars. He also wonders if the movie they were watching was the one they watched with his brother in law, and by the stuff he's thinking about, it seems he kinda feels as if Sunwoo is still clinging to BIL through him, but it seems that for some reason Sunwoo does care about him (I don't know why tbh. I mean, I want to see them together but bless this guy's soul, I didn't think it was going to be this way after all that happened).
When they arrive to the hotel he just tells Yuri to go home, as there are people who care about him there, and that hotel expenses will he too much to handle eventually; he asks if Yuri is better and as Yuri is still a dick, mocks him saying "I got worse because of you" (or something like that, I'm not fluent), so Sunwoo smiled and said "you should try to get better then" and handed him a piece of lemon candy. Yuri's expression was as if he was astonished at the kindness in front of him despite his attitude, and grabbed Sunwoo's hand without even realizing it. He let him go and went with the excuse of being worried about him drinking and wandering around, so basically asked him to go directly to his place. The rail at Ch21 is mentioned again but Sunwoo is seen walking on it in front of Yuri.
The last panel is him fidgeting with the candy wrapper, contrary to in FYL where Park gave him candy and he automatically threw it away.
It was sweet and tender, you can finally see Sunwoo smiling in various panels and Yuri making soft facial expressions and frowning less than usual. As I kept reading, I just thought about how good of a writer Park Nodeok was.
Next season starts in February 2021 (:

I do not understand how jiri is developing feelings but yuri should since it seems he fell in love with his cousin because she was kind to him.
I really dont get the older sister and the parents. Why she tried to slap him in ch.28?
I started to think maybe yuri is actually the son of the oldrr sister that is why they look so alike and the parents are so distant, but i dont speak korean so i am not sure what is going on....

Spoiler
Basically their mom neglect them and their dad is abusive, his sister (the real one) behaviour is the result from their parenting and yuri is the result from the three of them, but he also close to heejoo who is very gentle and affectionate. Yuri's sister (the real one) never get the affection from their parents but as soon as heejoo arrived to their home, she got all their parents attentions and affections, we can see she was a lil bit jealous of heejoo. The reason why she wanted to slap yuri was because after she told yuri to not thinking one dimensional, yuri said to her that she's just jealous to heejoo so yeah yuri hit it right but his sister also telling yuri the truth

Believe me, I don't understand HOW Sunwoo would be catching feelings either, but tbh, it mostly seems as if he just wants him and Yuri to be at peace since they work together and all, I don't think he's catching feelings now, he's just surprised Yuri's softer and more receptive.
As for the rest, Yuri basically told his older sister that she was just jealous Heejoo was loved the most by the family, that's why she tried to slap him, and the rest of the explanations here are on point, his family just didn't love him in the slightest, although it seems his older sister wants to make amendments but since she also lacked love and care, and Yuri's a dick now, she doesn't know exactly how to do it.

This is not even the 20th chapter, and this author's FIRST work had 80+ chapters. I SWEAR y'all it'll come, but don't expect it to be here less than in 10 chapters from here.
Also, like it or not, this won't go the typical BL route where one ignores the other out of spite so the asshole one can see how wrong he was. This author already wrote an amazing story where the main character was almost certainly demisexual and not with a very cliché development at all. I expect no less than these two helping each other to heal and going through some more shit as one of them has to deal with family abuse, and the other one with alcoholism and depression. I don't see this author doing typical, boring and overused BL tropes.
I did NOT expect this, it was horrible and great at the same time.
People complaining: It's tagged as horror and tragedy, what did you expect? lol
