Okay so overall it was a cute drama. I wanted to watch since I'm a fan of Infinite. I have to say the beginning episodes were really good and well written! However, -don't hate me guys! ^^- after a while the main plot started going downhill and became slow and repetitive. I really don't think it was necessary to drag it out to 20 episodes. I wanted to see more character development which I was only able to get with a few characters. There was also all this angst which I didn't understand where it was coming from, and other moments between the main cast which I found really hard to relate to. That being said, I hope to see Sunggyeol in more dramas, because he definitely moved up my bias list with this one~ ^^ I also enjoyed the angel world plot line and school plot lines which I wish were developed more. It had it's funny, cute, thrilling, and tear jerking moments. I really wanted to like this drama more, I really did but I kind of found myself pushing to finish.
