I don't know why the most people doesn't like this movie. But in my opinion; I have been so excited to watch it. I think the love between the male main lead and the female main lead wasn't pure but it still a "love". We can judge the feelings of others only because we don't agree with there ways to express them. The 18+ scene; even it disgusting me a little; but still so hot and you can feel the love in those scene; it's so realistic. The ending is a tragedy for me; the male lead doesn't forget his love to the last second in his life though the female lead gave up on him and moved on with her life.
