he’s not even close to a red flag maybe a yellow flag at most. he was a total green flag angel in omega complex but here his personality is depicted as a little more “fake”, he doesn’t show his emotions easily, plasters a fake smile and leads mc on. he lies to mc acting like he never knew who he truly was and randomly acts distant but all of a sudden they start dating bc he can’t restrain himself .. yeah it’s simply just yellow flag since it’s impossible to read his intentions and makes me feel terrible for the mc who wears his heart on his sleeve, feel like bro is playing sometimes
I don't think it is that simple. Dohyun's past is sad and they manipulated him as well, he gorw up with bad ppl around him specially Yeon's family (iykyk), he was desperated to get out of where he was and they were the exit, however he fell in love during the process and ran away bc he though he'd lost everything he had in his life as Yeon's family do have that knid of political power. To me, they were the real red flag. Don't get me wrong, I'm not saying Dohyun shouldn't be honest with Yeon, is just that when you're afraid to lose the only good thing you have in life, you panic, and that's why something ppl lie. Dohyun started with a goal in the past; however in the present he's just madly in love, but afraid.

I remember reading this novel and hated the ML. Omega complex is much better. Hated that O was hooked into thia knowing how red flag the ML is. Fuck you manipulating bitch ugh. He was portrayed as nice in omega complex (he is nicer in the mc there than here imo). If this goes the way the novel does, I would drop it. MC DESERVES BETTER! I still feel sad for him (๑•ㅂ•)و✧
