1. STORY Right at the beginning of the movie, after seeing the main lead actress we might know the ending directly, at least we might know good ending or bad ending. But I loved watching it, like how they fell for each other, their romantic chemistry, even though the boy couldn't talk! I cried at the ending. 2. ACTING/ CAST Bo Young did a great job. Joong Ki did an excellent job. How could you act that good Joong Ki? The rest were pretty good too. 3. MUSIC I loved the song which Soon Yi sang with the guitar. What a beautiful song for a beautiful movie! 4. REWATCH VALUE I'm not sure about this cause if I rewatch it I'll have to cry again 5. OVERALL (please don't read if you haven't watch it, SPOILERS AHEAD) Hmmm 9.5 cause I can't stand how she went away, left the boy again, alone... And how long will he have to live on? He didn't turn old or something... but I have to admit it makes the story feel much more painful.
