Basically Rule breaker by Lily Morton but in an omegaverse setting.
Based on the reviews I expected Keith to have lit Yeonwoo on fire at least once. But he's just like any other alpha-hole I've read before.
It's like the manga/story itself knows it's trash, and it's not trying to be anything else. You're not supposed to take it seriously, or use it as a manual for a healthy relationship (lol).
My expectations were low so I loved it lol. Or maybe I just don't have good taste.
