I decided to watch this show for two reasons: first, I have just watched Moon lovers Scarlett Ryeo and  I have never though it would break my heart as it did... So I needed something to laugh and have fun. For this reason I was looking for something light to watch, and I remembered the video of this show's song "Beautiful, beautiful" that I have seen countless times on YouTube, so I decided to give it a try. It was the correct choice. I liked it very much because it made me laugh a lot. I'll never forget the La La Land scene.
Ok, it's not perfect, the story plot has some lacking -as almost always when time's travels are on it-,  and sometimes it goes too slow (it would have been better 25 episodes or so instead of 32). On the other hand I don't know why but I found kind of difficult to believe the feelings and/or the acting of the female main lead towards the main lead.
But... It's soooo funny. And Yoon Shi Yoon it's so good in his role. Only with these two reasons its worth watching it, but also the story is cute, about problems and situations every one of us has to face in their lifetime: friends, family, work and dreams, and the seconds leads are ok too.
So, if you need something light to cheer you up, to watch this show and to listen the main song are really the best option to get it.
