Because her sister Su Xin went abroad to work, Su Zitong, who lived with her, was taken into Luo Yu's home to stay temporarily for a year. Although she is already in her senior year of high school, she still has a lot of time to tease the leisurely college student Luoyang. A misunderstanding caused by a strange combination of circumstances brought the relationship between the two to a freezing point. It was all thanks to Luo Yu's efforts that the two continued to live together. Under Luoyang's meticulous care, Su Zitong slowly realized that he was not just teasing Luoyang for entertainment, but also gradually couldn't do without him.
Concept: The relationship between two people who accompany each other is only separated by a layer of window paper.
