In this era where it is difficult for heterosexuals to last forever, what should homosexuals do if they do not have a marriage certificate and children as a bond and are not recognized by the social environment? This is a question that Yang Shu has been thinking about since he learned about his sexual orientation. Because of his family's sexual orientation, he kept himself locked in a closet and refused to come out until one day a girl knocked on the closet door, giving him hope, but he never thought that the door would be violently closed by another girl. He thought he would never come out again, but he didn't expect to meet him.
