Su Qingyan was considered by everyone to be the cold and arrogant eldest daughter of the Su family. She was very elegant, but she frequently failed in front of Lu Zeyan. Lu Zeyan, on the surface, looks like a romantic second-generation rich man, but in fact he is calm and reliable, but he likes to mess with this "iceberg lady". After an unexpected encounter, their fates became entangled, and daily pranks took turns: he deliberately added too much sugar to her coffee, and she secretly lost all his game account ranks; he carefully planned a romantic date, but she was duplicitous and pretended to be disdainful. The green tea around him was jealous and the yandere was making trouble, but they were all slapped in the face by the two of them working together with a tacit understanding. In the group's favor and protection, the two-way secret love gradually becomes clear. It turns out that the weakness of the arrogant young lady has always been the funny little ancestor who seems to be not serious.
