A university dormitory is crowded with five "drama queen" girls: Green Tea Lin Chacha with a weak appearance, Su Lianlian, a white lotus who likes to pretend to be a virgin, Zhao Shuangji, a scheming girl who is good at calculations, Qian Jiaojiao, a money-worshiping girl who is addicted to material things, and Qian Jiaojiao, an internet celebrity who likes to pretend to be a person.
They brag about their "sisterly love" to each other on a daily basis, then secretly change the materials in the academic evaluation, secretly cause trouble in the love court, and take advantage of each other in the social circle. All kinds of "bitch" operations are performed in turn, and there are a lot of oolong jokes. Until a health crisis in which everyone took the blame caused the five people to tear apart the "plastic" mask and expose their fragility and disguise. In the end, this group of "crouching dragons and phoenixes" who once fought against each other changed from fake sisters who undermined each other to real bad friends who can laugh and complain about embarrassing things, interpreting a period of absurd and heart-warming college youth.
