In the novel didn't he meet both euigeon and oh minseong outside his apartment? some things are changed for a more compact plot ig

Here... there's spoilers though so go back to the first chapter to avoid. It's not translated, I just use mtl

Not the brother being hotter and having more interesting vibes than the ML. The ML has no likable personality traits

Right, why not?? This is a guy who could appreciate Seowon as his own person, not as someone who serves his needs who can be controlled. I already read the novel so ik how this goes but damn the manhwa really made Jiwon (the brother) more interesting than I had imagined, they should change the story
Jungwoo is one of the first MLs I've seen in a non-omegaverse setting who just accepts his feelings and his physical attraction instead of bullshitting about it for hundreds of chapters. He was like yeah I've got a crush ig should I kiss him?
Yep! We skip the whole "I'm not gay" arc. Got to love those self-denying people. Who go on and on about not being gay, but end up being gay anyhow... x'D
