“Gege, what does cultivating feelings mean?? Is kissing when you eat someone’s mouth?? How are children born??” The 3-year-old Xiao Tu likes to chase after her ChangZhi gege and ask questions…

Ten years old Cheng Zhiyan had always seemed been studious and hardworking. However, when he heard these three questions, he was stunned and fled in an instant… until one day, a certain thirteen-year-old Xiao Tu pressed Cheng Zhiyan to the wall and kissed him.
