This movie is literally a literature teacher's best friend. There are so many realistic lessons and symbolism. They express Innocence and Guilt a lot.
The relationship of protagonists at first is pretty rocky but once they hung out more, things get adorable and sweet.
The movie is so powerful and leaves you fucked up. The story was welled written and the acting made it even better. I wished there was more romance but it still contributes fine with the plot.
I didn't expect the ending to be like that. The ending got me in a wreck. I really related to the male protagonist at the end.
You should at least watch it for GOT7's Park Jin-young.
