Mystic prince was good, but she later on gets twinkified i liked her earllier drawings more, and they have the forced childood romance between the ml and her its so forced there is no chemistry , the ml liked her beacuse she kept ignoring him from childhood, she had more chemistry with her bodygaurd .

Your BEST 10/10 romance fantasy or modern manhwas
preferably strong FL
I mean something that just makes you go wow this is it
And it should be completed I'm tired of the ongoing ones
