Xu Yao and Luo Qingyue have been childhood friends since they were little. When they were eight, Xu Yao's family stayed in Yuncheng while Xu Yao moved to Jiangcheng, separating the two for ten years. A decade later, they reunite when Luo Qingyue gets accepted into Jiangcheng University and temporarily moves in with Xu Yao. As they spend more time together, Xu Yao gradually falls for her. His tsundere childhood friend is adorably silly and irresistibly cute.
