10 Korean dramas that you would watch as a background 

So they are enjoyable enough to watch them but not as worthy to be totally invested

There are a lot K-drama I regret watching but somehow completed it for the leads:

1. Dream High 2 - flat

2. Paradise Farm - annoying

3. Goong S - boring

I watched both these dramas as a background when I first did and..

4. Love Next Door - like so many other K Dramas, 16 episodes was a lot, could only do it as a background watch after a few episodes 

5. Arthdal Chronicles: Sword of Aramun - was invested in parts 1-3, and I don't know if it was the 12 more episodes after three parts or the lackluster story, I just could not pay attention 

6. Once Upon a Small Time - It's a nice background binge. Not much going on. But I didn't not like it.

7. The Best Thing - Same as the other. I didn't not like it. Could watch in the background.

Those about don't sound like enjoyable dramas... 

8. My Demon - Watching at 1,5x speed while working, it was actually really entertaining, but I would have been bored watching otherwise

Wow, you're awesome. I dropped it after around 10 episodes iirc after trying hard to continue it. It's very interesting in the beginning, and the visuals was wow. But then it became meaningless since around episode 7/8.
