Zhao Yan'an, a sophomore girl in high school, accidentally turned into a boy after making a wish, while her childhood sweetheart Zhou Si turned into a banyan tree in the playground. She went to school as "Cousin Zhao Yan", and during the day she dealt with confessions from the basketball club and her mother's "pet mode", and at night she squatted under the banyan tree and complained, while in the shadow of the tree, he was lightly hitting her on the head with fallen leaves, hiding his jealousy and tenderness - this oolong magic became a sweet beginning for a two-way journey.
