I have been putting together a list of green/yellow flag omegaverse
https://www.mangago.me/home/mangalist/4233485/
Some of the other side characters are toxic too. So it's surprising that I love this manhwa as much as I do, especially considering what I said in the above reply, lol.
I agree with most of the other titles presented btw, too! There's another I'm thinking of but not quite sure of the name right now!!!!
The main couple in LS isn't toxic at all, nor is the one from Hyangyheon Text, but the side characters and the fact that the author has a weird fixation. The side characters yeah they are not always good. Love Shuttle was the very first omegaverse story I ever read so it holds a special place in my heart

Can anyone please suggest me a green flag omegaverse like this one
