Story wise this was a really well written drama, There were quite a few surprises they gave which I defiantly didn't see it coming. Like they made me believe I had everything figured out but they dropped those and suddenly the story became even more perfect and emotional, This was definitely a emotional roller caster, Maybe you can't feel this in the initial starting episode but when it comes there you cant help but cry with the leads. I have to tell the acting of the leads is another reason why we can relate and feel their pain. The cast really did a good job .

Personally for me the only flaw was the characters. I don't know for me I would have loved if they have a bit more to them. The characters for me was a typical and cliche characters from youth romance drama. Maybe it is if we forget the whole time travel plot then its really a youth romance drama. The characters was my only complain from this drama other than that the drama was perfect.

I have to say I really loved the music. For the music producer I have to give hats off, really I felt the youth, love and pain through the music. The music was really perfect and it went so well with the scene and made it even more enjoyable.
