Jin Yu, a girl who grew up in an ordinary family, has a gentle appearance but is actually a sinister little devil. On her 18th birthday, she went out to celebrate with her friends but encountered a criminal swimming beast that escaped from heaven. After being seriously injured by the swimming beast, a dragon claiming to be Ao Tian appeared in front of her. In order to survive, Jin Yu had to agree to live in Ao Tian's body. The exciting and thrilling "cohabitation" life of one person and one dragon begins... But Jin Yu gradually discovers that Ao Tian's identity seems unusual, and he even understands himself better than his close friends who have known each other for decades. What is going on... I have only written short stories (because of laziness), and finally made up my mind to do something big~ However~ due to academic reasons, I will update from time to time~ cough cough
