It's a well rounded story about parallel universes, and if you like these light sci-fi kind of drama (like Someday or One Day and First Love Again) you might like this one as well. The problem here is that the characters lacked emotion. The best one is the female lead's father, but the rest didn't get me attached to them. When the actors changed from child to adults I couldn't feel the connection between them either.

So, if you're looking for a romance to get emotional and root for the leads, I don't think you'll find it here. And I don't believe it's just the actors fault, the script didn't make them close either.. it felt like they didn't really care about each other. At the same time, it's nice to have a romance without it being over the top, I guess you need some balance and for me this wasn't enough.

Despite everything, it's the kind of drama that makes you want to talk about it (hence this review) cause it leaves you thinking and it's pretty interesting.
