hmm... right now there is a slight possibility that Siwon can end up with his best friend (the orange haired on that got kidnapped) because we all know he likes siwon and you can see how the author hints that Siwon's best friend felt a glimmer of hope that he could be with siwon when siwon explains to him that he might not actually like kang jinha. so idk, we can't exclude siwon's best friend from the equation, he's a possibility too. we just have to keep on reading. but what you're saying might be possible too, all these characters are unique, such as how lu xuan run isn't some cookie-cutter antagonist with no emotions and personality, he actually has a heart and jinha isn't some cookie cutter protagonist that has zero flaws and always saves the say, so it's hard to predict what anyone in the manga will do.

hmmm I don't know. because this is the author's first work, I'm not sure if she's the kind to make her manhwas classic/cliche love stories, or if she's going to surprise the readers with a totally different outcome. Maybe judging by the cover - siwon x kang?
personally, I'd love to be surprised by the mangaka (but she has to make it make sense too though lol). I liked your bff theory!
i dont think go siwon is trash like everyone says. I just think he's portrayed like that because him and kang jun just aren't compatible in a relationship, so they have more downs than ups. i think siwon and lu xuan run make a better couple. besides lu xuan run's crazy tendencies, xuan run knows how to handle siwon and siwon reacts much more differently to xuan run's personality than kang jun xd. kang jun doesn't push things he waits for his partner ask or do what he wants, but xuan, is pushy and isn't very patient, and I think siwon's better off with that type of person just because siwon doesn't like asking for what he wants because he gets embarrassed, and lu xuan run just goes for it lmao, he'll kiss siwon if he feels like doing it but he respects siwon in some way though, he won't rape siwon or anything..........i think
