This manhwa was literally posed as a green flag top and I think its totally valid for people to read and slowly find out how such a red flag that guy is and to not defend Su-ah which alot of people love to do . This is progressing story with no raws so everyone is going to be in their feels when reading with nothing else to talk about relating to this story.
this was never tagged not indication that this was a green flag. y’all just assumed that. heck, the signs were these even on those flashbacks when they were kids. and as you said, the author made the character reveal "gradual" but here yall still reading it, which means you like it, then whine about it. like i said, just hypocrites

I’m so tired of the Yaoi police morally posturing under every manhwa that showcases even slightly dark relationship dynamics. Not saying you can’t criticize the manhwa or dislike the direction it’s going in but some of you are just annoying. If you want to read a fluffy story you need to fuck off tbh. I could tell Suahwas going to be crazy and that their relationship was fucked up within the first few chapters. I don’t get why you’re all complaining now. Let them work through their problems.
