There are seven boys in a university in Beijing who became brothers by fate, but they were nicknamed the "Seven Fairies" by outsiders. The eldest brother Hao Yinluan and the second brother Li Jiaocheng are entangled with each other and have no good results. The third brother Huang Yifei breaks up many times before he realizes that he loves his first love the most. The fourth brother Liu Yiqian comes out despite his brothers' advice. The fifth brother Shi Yaqing likes straight men but is teased. The sixth brother Pu Lanke is innocent in nature and is eventually poisoned. The seventh brother Hu Ziwei is the most dissolute but gets involved in campus disputes. Among them, there are plots such as the boss and the fourth old meeting each other, the third and fifth old people helping each other, the second and the sixth old people comforting each other, etc. Everyone is welcome to taste it.
