I'm kinda sure he will stay an omega. his obsession with sunjeong maybe bcs of he's mentally unstable due to his damaged bond. Sunjeong's the only one taking care care of him, almost like his every basic needs, then it rooted as feelings that turned into smth more, combined with seing sunjeong getting fucked by his customers on daily. Maybe just MAYBE this is why the doctor is kinda eager for seok's medication, bcs he knew it would turn to be smth like this

like I think he’s so cute and he would look really cute in a side couple but like, why he so obsessed wth MC. but… also… pls go to check up don’t die, u have so much potential as an omega…. Don’t be an alpha pls
