Literally thank you, everyone thinks Jae is a walking black flag. Yes he doesn't have the nicest personality, nor does he do good things that comes from his heart. If anything Jae an orange flag boarderline green and red whenever he chooses to be.
There are worst I mean WORST MAIN LEAD EVER, like Cesar from roses and champagne not only did he physically harm Lee Won but R@pe him for 8 days straight.
And then we also have Kwon Hee Seo from tree without roots that mf is CRAZY and black flag behavior. Jae doesn't even compare to what out there, like you stated there are seriously seriously stranger and deranged abusive main lead that takes the cake.
Don't even get me started on Kwon Ido the way people praise his ass for being a green flag when reality he a black one.
Right?! Like bro there r so many fkd up BLs I can list rn that would put this one to shame in terms of FKD UP lmao. There are many that live in the back of my mind that I wish I never even read because of how fkd they were. Σ(っ°Д °;)っ Ya'll ever read Killing stalking? tht MF Sangwoo( ̄∇ ̄")....
