I really dont watch k dramas but I really like lee jong suk from w, and while you were asleep

my favourite female actress is the main actress from ( oh my ghost ) drama.

So ji sub: (I like his acting style. Its unique!)
Oh my venus
Master's sun

Shin Min-a:

my girlfriend is a gumiho

Gong Yoo:
Cofee prince

Lee min ho:

My other favs are
falling for innocence/Beating again(I love the comedy scenes)
Kill me heal me (multiple personality disorder. Made me laugh and cry. Its a emotional roller coaster)
Its ok its love (love the couple and the plot! phychological)

Well that's enough.there are many more amazing ones but I gave a lot already (￣∇￣") Hope you enjoy it!ヾ(❀╹◡╹)ﾉ~

my absolute favorite female lead is oh my ghost with Park bo young (she's also in strong girl bong soon ! she is v good at changing her personalities)

male actor : Ji soo he always plays the sad characters but i love him a lot ٩(๑❛ᴗ❛๑)۶ (also in strong girl bong soon + cheer up !)

lol you've only watched 4 so I guess you're not too familiar. I've watched so many K-dramas that the usual cheesy types don't cut for me anymore. Trust me, when you watch enough, you will find that most K-dramas nowadays are complete trash, corroborated by the fact that they have dreadful to mediocre ratings.

If you're looking for fresh K-dramas to watch, I'd suggest Signal, Misaeng and Sky Castle, all of which were hits in Korea but not well not internationally because they aren't romantic. Signal has my favorite female lead (strong badass police officer) and Misaeng has my favorite female and male leads (hardworking underdog and capable woman coping with classism and sexism, respectively, in Korea)
