Xuan Yongnuo met Chu Xu during his four years in junior high school. Within four years, he found that he fell in love with this boy who was gentle and tolerant to him. The girls in the class noticed the ambiguity between them, and turned their gossipy eyes on the two of them. When they accidentally learned of Xuan Yongnuo's feelings, Chu Xu ran away. His timid escape made Xuan Yongnuo feel pain in his heart. In the days that followed, he tried hard to forget Chu Xu. It was not until Liu Ziyan bravely and domineeringly held his hand and gave him a lifetime of warmth that he fully understood that maintaining same-sex love only requires the word "courage."
