It was cute but, you can drop Drunken to Love You
I dont know anything about Japaneses dramas so...drop art of seduction
From bahar's list: There are so many I haven't seen, but the ones I've seen, ALL CLEAR!
Keep Healer, High-End Crush, and Bride of the Century
Drop Moorim School and High School Love On unless you really like the idols
mhhh drop Uncontrollably Fond U.U
@Ariko You're clear from my limited knowledge & u should definitely pick up some On-Hold cause they're mostly great if not amazing ;)
^ Drop: Whisper, School 2013, & Tomorrow With You 

Other people may disagree with me but I saw the first 2 eps of Whisper and didn't really like the camera angles and storyline. 
As for School 2013, the first 3 episodes were slow...... Which made me sad because it is a Lee Jong Suk show and he acted with Kim Woo Bin.
Tomorrow With You WAS SO SLOW AF. GOD. I couldn't believe I actually finished it but it was pretty boring and slow paced.

Basically if you are a person who loves dramas that catches your attention on the first few episodes, don't watch the School 2013 and Tomorrow With You.
Pick up Signal Bae!
Drop Legends of the blue sea :)

*I'm truly sorry for the next poster*
*I'm truly sorry for the next poster*
Why?  I have more things on my on-hold list than you do :)

Anyway, it's safe to drop Sword and Flower, I'd say.  I finished it, but I'm not quite sure why.
DROP ALL CHinese dramas HAHAHAHAHAHA
