Ren Siyu, who is ordinary but has a lot of love, is attracted by the cool and handsome Wang Pengke while he and Kang Yan are tacitly fooling around. She thinks that the sword jointly signed by Cupid and Yue Lao has finally come to her. Unexpectedly, the sword traveled across the ocean and was guided by the sea to become the Sword of Neptune. It is the secret joy of having an ambiguous relationship with the boring school sweetheart, the stubbornness of being an enemy of the "world" in order to protect the one he likes, and the growing pains of being exposed to rumors and finally having to bear the pain of resolving it alone.
Purpose: Everyone you meet in your youth has a mission, either to give you pain or to give you guidance. In fact, it is both.
