Too much message in a short movie. Too much to the point not anyone can understand the message. This movie takes place in highschool but the story is not that simple. Idk, maybe if they make it longer, we will understand it clearly. But by giving an ending like this, the director wants us to think and reflect this to ourself. If we feel those friends are selfish, are we better than them? If we feel hyeon jae are selfish, do we can communicate our feing better than him? Thank you for an interesting movie. Worth to watch. Worth to think.
