I'll assume the writers might have wanted to go for a deeper story/meaning about when do one actually start noticing that you love... or like someone...

Firstly the movie itself wasn't bad, but not at all great. I'm surprise at the overall high rate.
I felt there was something missing from this movie and the sound track didn't match it at all, though very catchy - There's much more I can say about this but it would give away the ending.
The story line was given away within the first 10 mins, and even though the movie was already only an hour and a half, there was time to take a run-through memory lane. The beginning and the ending did though add up together.
