Not sure if I really liked this, all the production and technical aspects are okay, but the story made me thinking about what really was trying to tell...
The main question is if Homosexuality is a sin. Even if in a moment there's this explicit put in text and said that God love all, also it's said that is a sin and the important is regret it to be forgiven. All the subtext also reinforce this idea, the serpent nightmare, the clothes were Yo Han start using white but get darker till the black when he "sinned and fell into temptation" contaminating himself because of the "predator" Joo Won, the prayers... The end indicates a cycle of events still trying to resist.
So in the end I think even if it is kind off realistic, it is too much biased, I don't think that brings any real lesson, any characters development or really any help in anything to this group of people that already suffer so much in such homophobic society.
