Hiding her identity so that no one will find out, Ge Yan has no choice but to have two personalities with her obedient childhood sweetheart Nie Yu. One is "Brother, I'm injured. I feel so uncomfortable. Come and rub it for me." The other is "This little injury is nothing. Leave me alone. Hey, please don't do anything!"
