I'm at a loss for words. Started watching this because of the fun premise, stayed because of the way they shifted the movie route to something way more entertaining and mostly because of the great acting.

Yeah, you can't talk about this drama without mentioning the acting, specially Lee Dohyun. That boy makes wonder with his role, making an already good story become so much more because of how incredible his performance as the main role was. And the rest of the cast is not that far from him in terms of competence, Kim Haneul shines through her captivating and charismatic female lead; it's probably impossible not to root for her at every chance possible. Yoon Sang Hyun gets fewer parts than LDH (which may seem a bit weird since he is listed as main role but very understandable considering how the story needs to be developed) and he's for sure a veteran, a very skilled actor who deliver some great acting whenever he can.

Now, the story itself. It's basically the 17 Again movie for the first two episodes, which may lead you to think this is going to be just a shy remake of another story. But oh boy, by episode 3 they just leave everything behind and the drama really begins. And it's a journey, a very weird and spectatular one. It's almost impossible to get bored or frustrated because the problems are solved in a quick, effective way and it doesn't affect at all the overall flow. And it's very refreshing too, without being too preachy about it. They touch on some delicated matters; like divorce, sexual harassment, bullying and never in a "in-your-face" type of approach. It's all very subtle, very light-hearted and the most emotional scenes are usually connected to the main leads itself, and the struggles they need to face.

Still wondering about it? Just try the three first episodes. If by the end of episode three you're still not immersed, it may not be for you. But if you're into heart-warming and funny stories, please give this one a go.
