The relationship between Lip and the teacher is warming up, and the teacher's special family contract makes this experience reasonable. Cam's business in college is getting better and better, but mixed marijuana has caused trouble. Among a group of college students who lost their minds because of drugs, the humorous computer student jumped off a building and broke his leg. Lip turned to the female teacher for help, and with the brotherly kindness of the broken leg classmate, the matter was finally solved.

But Lip euphemistically expressed her hope that Cam would leave. Under Mickey's care, Ian's condition seems to have shown signs of stability, but Ian doesn't like such a dull day, so after a beating, they enjoy remembering their happy life and singing home.

Unexpectedly, the revenge of the elder sister led to the report that the military organization arrested Ian, and everyone was sad and angry under the curse of the elder sister. Debbie and Derek are going well. Accompanied by Fei, Debbie went to the Family Planning Bureau for a physical examination, attended Derek's family dinner and got to know her relatives.
