I love every bit of this show, except for tiny one. Yeah time travel is an incredibly complex plot to cover and yes this show makes it seem like a child's play, therefore you should NOT except consistency in that case whatsoever, you'll understand me if you've watched 12 Monkeys or Dark. But this show isn't actually about time travel anyways. It's about friendship, love, family. It's about forming sincere bonds. It makes your heart melt in some scenes, makes you laugh out loud in some others. Not only do characters bond with each other but you as the viewer also bond with them. It can easily become anyone's comfort show. THAT is the reason I love it so so much.
But...

I really couldn't bring myself liking their ultimate end. I understand that Cheong-ah comes from a wealthy family and she made up with her father in 1995 and that means her new future could change in a way. But I don't think they needed to become this forefront successful "business" family to be "better". For me their former family was also so sincere, lovely, and just as enough. They didn't have so much money before, but they had everything else. Did they really needed to be ultra rich and famous to be happier? In fact when I saw that they happened to become such big famous people as a family, I kind of dissociated with them. That is my only criticism and hence my rating. I wish we could see their new future condition in a more sincere setting rather then being exposed how they became high society. The writers really must have thought this is the most fulfilling ending: seeing them rich and having power. I couldn't disagree more. I would prefer to see them for example having their breakfast on a Sunday morning, in which I-chan's friends happen to be there, chatting and laughing together. But I don't know, maybe that's just me.
