In order to train students to write good compositions, Teacher Lin from Class 2 of Fourth Year came up with a method to ask students to write diaries every day. Since then, members of the DoDo impostor team began to record their daily encounters and feelings in diaries.
Among them, Mo Duoduo and Charlie solved a murder case in a secret room on a rainy night; Yao Tingting met a strange boy on the weekend, who turned out to be someone who had disappeared long ago. Why did no one know about his existence? Tiger Shark's cousin went missing during an outing, and members of the DoDo adventure team went deep into the jungle to rescue...
Mo Duoduo: I will definitely become the greatest adventurer and detective in the future——
Yao Tingting, Tiger Shark, Fuyou: Dream on, Mo Duoduo, dreams are the most beautiful!
