Ahhh there's just too many options out there~! haha tell us what kind of dramas you like...suspense? romantic comedy? saeguk (historical)? etc?? It'll help us give you lots of good suggestions! =)
If not, you can check out my drama list below...one's with the hearts beside it are my favorite for various reasons (mostly it means I was super addicted to them ahah)
i would say BOF, you're beautiful, coffee prince, my lovely samsoon, but then again in depends on you and what u like. dont be afraid to try something new even if you're not sure and dont always follow a drama because ur favorite boy/girl idol is in it (I've learned that lesson countless of times)
