DOTS 不下去

Recently, like 6 out of the 10 ladies you probably know, I started on Korean drama. 

I watched 她很漂亮 recommended by Bree. But it's a bit irritating that u really need to fully focus Coz need to read the subtitles. This means I can't be doing something else to let it play in the background. Haha 

So the next drama I naturally chose the current raved about Descendants of the Sun! Who knows, I dozed off amidst episode one. 

Decided to give it another chance to episode 2... Now I'm at 3.... 

Can someone tell me what's the rave about!!?
