It was lighter than I expected, but it kept me at the edge of my seat. I was hooked immediately by the first episode and I was glued until the very end. Pacing was good, the writing was consistently progressive, and I love its portrayal of the reality of how fickle human emotion can be (I think it was between Episodes 1-4). I found myself laughing really hard, ugly crying at some parts, and swooning over so many scenes. It's near the likes of Goblin and some details reminded me of My Roommate is A Gumiho (though this was released first), but it was unique in its own way and I think I like this a tad bit more. Plus, casting was perfect and so was the distinct OST. Masterpiece. I love it so much and definitely something I'm recommending to friends.
