Very bad ending !

I didn't have high expectations with that drama but I started to enjoy both story and characters...until the last episode.
That ending was stupid af and destroyed the whole drama. Is it worth watching ? Well if you're in between two dramas and don't want to watch something where you have to use your brain and just relax and laugh a bit, just go for it...otherwise...choose something else. Very very disappointed. What a waste of time. It could have been so much better.
