i thought i will take a pass on writing review for this. but synopsis not entirely right and i think it should be good if one knows that its not a fun, cheerful movie, but is a dark one with sad ending that hits you hard. we find 4 friends getting into hasty trip to drop one of them into military. but a mishap happens involving tragic turn in their lifes. so they fight, suffer, lose themselves and much more. what exactly happened? will they hang in there? will they stick together? will they be able to come out of this? ji soo is incredible.he gave a soul stirring act here. i love all his characters in recent times. ryu joon yeol excelled in his own way. rest were really good too. the way they pictured their lifes is different to. the actors who played their parents were decent. i just love halmoni here. it was painful for me to watch her. ending is sad, frustrating. yet i liked it. i love the way characters ended up realistically. its hard to digest. i wonder why i exactly i liked it. i love the way its not predictable. so yeah, watch this for good story packed up with great performances. its worth your time.
