I am just 21 years old but this made me miss my school days so much . Everything flashed before my eyes i could not stop crying . Eveything is just too fast these days maybe i am an old soul it made me want to go back to those days .Coming to the movie review i liked the movie just the ending .... cant we have a happy ending was it necessary to seperate those two .I really wanted them to be with each other their last moment was my favourite part of the movie brillantly shot ,the emotions were too pure . Why just why ????? I am just to frustrated .... Too many good cameos storyline pretty simple but felt new .Younjung's acting was on point ,the male lead when he was crying in the train i was also crying with him .... allover good movie but i will not rewatch again it will be too hard for my heart
