This movie feels so much real and bit sad in the end.
Story is written so good, you actually start to feel it right from the begining.
Screenplay is completely different, unlike regular movies.
The movie is about how happy or blissful one may feel when he/she fall in love with someone, and how much ones heart can break when he/she realize his/her partner haven't have the same feeling for them.
In the climax the female protagonist "Summer" explains why she can't or she didn't love the male protagonist "Tom", will make you feel sad for "Tom", but indeed it so true.
Don't miss this movie.
