Keep: Hello Monster 

Lucky romance, Coffee prince, My princess, School 2017, Strong woman do bong soon, The heirs, To the beautiful you, W, What’s wrong with secretary Kim > PLS keep them !!

Jealousy Incarnate and My ID is Gangnam Beauty - since you have many other really good and must-watch dramas - unless you finish all those or you are really really bored and these are the things you can easily watch .. I'd suggest you drop them

Jugglers - honestly it was just boring

Drop: Because of You

Keep:  

- Save Me 

- Skate Into Love and My ID is Gangnam (but only the first half of the series for both,, very good but then it begins to drag ugh)

Keep: 

Chicago Typewriter
It's Okay, That's Love
Just Between Lovers

Clear (mainly because I haven't watch a lot of the drama in your plan to watch and drop list..) 

Don't bother to watch: Blacklist

Give a second chance to: Strangers from hell (I would add Prison playbook, but since you have watched until episode 8 and you didn't like it, it probably isn't in your taste.)

Restart: Hello Monster

Keep: Limit

Drop: Guardian 

                    

Keep: 

Descendants of the Sun

Just Between Lovers

What's Wrong with Secretary Kim

Drope: lets eat 2

Keep: Rooftop prince

Drop: Shut up: Flower Boy Band

Keep: Hwarang

Drop it! > Perfect Couple 

Keep It! >Oh My General
