MOST HORRIBLE ENDING EVER!!!

The overall story was good, and would've given it more stars for the story but the ENDING was horrible. Wasted my time watching the c-drama and ended like CRAP!!! Nothing resolved as everyone was saying. If you haven't watched it, I wouldn't start because the ending will just leave feeling like I do right now..After watching this c-drama, I am afraid to watch another if all c-drama endings are like this. I've seen some horrible endings k-drama, p-drama and a-dramas but this is ranked #1. I hope they make a season 2 or something
