Secret Garden (Ha Ji Won unnie is here too. This is my top among the top drama. I rewatched this a couple of times. This is just my thing) ---OOOPS YOU DROPPED THIS EVEN THOUGH YOU HEART HJW?? WHY?? Anyway, probably this is not a cup of your tea or probably because it started soooo slow. Or just maybe your otp is JCW-HJW. I love them both as a pair and love them both as individuals so I can watch them even in separate dramas....
Healer (Ji Chang Wook is the male lead. I love him and there is also a great chemistry between the lead)
Fated to Love You (Korean and Taiwan, both are good)
The Greatest Love (Gong Hyo Jin unnie is here too. I also love her. Since you watch, IOTL w/c is one of my fave as well, you have to watch this as well!)
Reply 1997 (So far the best Reply among the series. Currently watching 1988 as well, its good but 1997 focus more on the romance rather than family. The chemistry between the leads is just overflowing!)
Rooftop Prince (If you are not a fan of historical dramas, this can be your gateway to one. Thisis a drama that is somehow historical but with a twist.)
Kill Me, Heal Me ( It's okay, that's love rival but more exaggerated a bit --7 people in one body. YEP! No kidding! )
Emergency Couple and Cunning Single Lady (both divorced couple, have to work together because of a job. Both recommended! Plus Mong Ji is in EC. hehe)
Bride of the Century (I can say that the female lead is absolutely good for a newbie actress plus Lee Hong Ki is here <3)
Top 3 movies that I ABSOLUTELY LOVE (Warning: Tear Jerker genre)
Windstruck
Miracle in Cell No. 7 (It's on your list and I also gave it a 10/10 rating. You can watch it in youtube! I rewatched it a couple of times. Worth it!)
Rockin on Heaven's Door /Our Heaven here in MDL
I want to give more suggestions/ Just check my list. i think we somehow have the same taste in dramas and fave actors and actresses a bit! ) ^^
