There were times when I felt like the story was rushing and there were many holes. Like the first 3 year gap came so quick and they really didn't explain what exactly happens to boy who died. What happens to all the friends, what happens to Min Su's boss at the end, but in general the story was different and cute. I also think that the actors saved the movie. They made me feel something different yet beautiful. As for the gaps, the editing was bad, I couldn't find the prefect transitions during all the time gaps. Long story short, I think the person needs to watch this in order to understand what I'm trying to say and agree or disagree with me.
