Xu Yuxiu lost his mother when he was 16 years old. His father owed money. He watched debt collectors beat his father. In desperation, he had no choice but to work part-time while going to school. As a poor student, he could not make friends in school. When he was 15, he met Xu Sinian, who had remarried. He was sunny, warm, and like light. He didn't despise Xu Yuxiu but instead made friends with him. His vague concern made Xu Yuxiu, who lacked love, very happy. He wanted to like Xu Yuxiu, but he didn't necessarily have to be a man or a woman because he fell in love with Xu Sinian.
Concept: Their love is sour and hot
