Be My Mysterious Ghost. (Yanfei X Hu Tao)

In the dark of a moonless night, Hu Tao stumbles upon a terrible scene: a group of 3 people standing over Keqing's body. Ignoring her own safety, Hu Tao intervenes. With a swift and desperate move, she uses her Vision to forcefully seal Keqing's grievous wounds, stopping the bleeding but at a terrible, agonizing cost that plunges Keqing into a deep coma. The men flee, leaving Keqing's unconscious body and a bewildered Hu Tao behind. When Yanfei, ganyu and kia finds them, the scene is misinterpreted, and Hu Tao is arrested for the crime.
Yanfei, a rising star in the legal world, is assigned to the case. She seaming ignores all evidence that suggests Hu Tao's innocence, including the strange, unnatural nature of Keqing's wounds. Instead, Yanfei manipulates the facts to build a solid case against Hu Tao, securing her a reputation for being ruthless and brilliant.
As Keqing remains in a coma, until woken up by kia with the help of furina. It was Furina, the theatrical and fiercely just former Archon of Fontaine, who ultimately broke the case. Unsatisfied with the shoddy evidence and Yanfei's rushed conclusion, Furina used her unparalleled knowledge of law and dramatic flair to expose this in court with the help of xiao and other friends.
