anws i read it, IT'S SO GOODDD!!! the artstyle, the storyline, and don't even get me started with the plot!!! the characters personalities and tropes are also great, the whole manhwa basically became a new favorite of mine, very grateful for u to recommend it!! but as for the yellow flag major kwak, i agree, but more like... orange flag? HAHA i read the whole manhwa (so far even reaching to the raws) and he's really the mixed signals final boss bruh ( T﹏T ) still, i think he's just balancing his love and work life cuz he's too powerful yk ;; STILL, i just think he has a weird obsession towards dr. seok, or maybe just an observation

okay so you hate red flags but u offered me black flags... ok thank u for this one then... honestly it was fine for me, considering that this manhwa gives off killing stalking vibes except the top has father issues instead of mother issues like sangwoo had. i guess u could say i endured more terrifying abusive manhwas than this that's why i'm fine with it but i kinda don't fw the top slapping the bottom in front of his brother... i mean imo he should probably not show that side of him except for the bottom cuz it's rlly weird to do that in front of other people than them.
yo so i've been drawn into yellow flags these days and i just realized it now that i love it when both bottom and top are yellow/red flags to each other (ex. Checkmate, Payback, Eighteen's Bed) so i want y'all to recommend me bl with both red/yellow flags who'll eventually fall inlove w each other nd i'm not talking about the bottom being soft or angelic, GIVE ME BITCHES I WANT BAD BITCHES PLEASE I WANT THEM JUDGY AND STOIC
