I usually don't watch trailer so assumed it a different story by watching clip of it. But it was totally different haha. I actually don't like these kind of plots but I'm happy I watched it and liked it. But again the same complain with Kdrama. Why don't they give justice to their 2nd lead couple? It was so good but they let it hanging. I read a comment that they are getting their own movie but don't know if it's the continuation of the same story or not. I hope they give the required screen time and proper story ending for the 2nd lead for once.
