Love: A great FL and ML, an interesting plot, nice art
Hate: Cheating, an annoying ML, an airhead FL, concubines, when the characters are children for like most of the manhwa (I am so impatient), a huge age gap, grooming (sorry but the ones where the FL basically raise the ML are weird to me)
If you have the same taste as me, this is the list for you lmfaoooo (consists of manhwas, manhuas, mangas)
