I love time travel stories. I love stories where characters try to fix issues in their past (like the film The Butterfly Effect). So far, I like this.

This is only the second drama I've seen with Krist. He's still pulling weird, but funny, faces! His character (Kawi) is a bit of a loser who can't seem to get anything right. I feel for him every time he hesitates as it feels so relatable. I feel for him every time he wants to be close to the girl he likes - Pear (Aye) - but doesn't know how to do it. It's relatable because it's hard to put yourself out there and hope you won't feel crushed. He feels utterly crushed.

I find much of this interesting because hindsight is an incredible thing. We assume that if we went back to a particular time or place, we could fix it and it would all be OK. In reality, how could it be? We would only be accounting for our effort and not of other people. There's a domino effect in everything: a slight nudge in a different direction must make everything that follows slightly different...surely?

What I like: Krist's acting. Gawin's character (Pisaeng's cool hotness). Aye's lovely character (Pear)
What I don't like: The whining of Krist's character - act your age and take a chance (but it is relatable!)

I was surprised by the transformation of Krist's character from whining and annoying university student to wise and mature young man. It was a good transformation and beautifully acted by Krist - I believed every version of the character.

I admit that the last episode brought a few tears to my eyes. It was sad, thoughtful and joyful.
