Romantasy novels with cheerful and morally-grey ML

Hii, I'm looking for some romantasy novels with a cheerful and morally-grey (or has some dark side at least, bcs it's more fun that way) ML. Btw, I prefer guys who give energetic vibe instead of gentleman-type character.

It's even better if it's slow-burn and has angst as well:D

Thanks in advance!
