Jingsu

Jingsu is the slash ship between Lin Shu and Xiao Jingyan from the Nirvana in Fire fandom.

Before Chiyan Conspiracy
Lin Shu and Xiao Jingyan grew up together, due to the fact that their parents were close and that they supported the same crown prince, Xiao Jingyu. During the first episodes, Lin Shu has a flashback that shows him, Jingyan and Mu Nihuang playing by the river.

Before Lin Shu left for Meiling, he jokingly asked Jingyan if he would bring back the legendary pearl from the South Sea. When Jingyan returned, Lin Shu was nowhere to be found, but the pearl still lies in Jingyan's room, untouched.

After Chiyan Conspiracy
Jingyan continues to live life as a prince. He is often outside of the country and refuses to take part in the fight for the throne. Besides, the emperor doesn't trust him enough.

Lin Shu returns to the palace, this time under the pseudonym Su Zhe. The first time Mei Changsu meets Jingyan as Su Zhe, he requests to help Jingyan acquire the throne. Jingyan is surprised, but accepts the request. After Lin Shu appears to have refused to help Mu Nihuang, Jingyan lashes out at Lin Shu, accusing him of being like the other cold-hearted people. Lin Shu is forced to promise that he never would hurt any other people.

After a long hour of talking, Mei Changsu stands up and instinctively touches the rusted bow displayed next to him. His body now is obviously different from his original self. Jingyan stops him aggressively, but soon realizing his mistake, apologizes. Jingyan comments on how Mei Changsu reminds him of his old friend. Mei Changsu smiles and forgives Jingyan. He remembers the times that they spent together, and how Jingyan was able to secure a house earlier than he was.

Mei Changsu initially refused to rescue Wei ZHeng. This made Jingyan incredibly angry, even locking Mei Changsu out of his manor and prompting Lin Shu to address him by name instead of an honorific. Wei Zheng was the only person who knew what happened at Meiling, and Jingyan had always longed to know what killed his friend. Because Xia Jiang suspected that Mei Changsu was stopping their plan for the throne, he imprisoned Mei Changsu in terrible conditions, at one point forcing him to take the Bingxu pill. Said pill kills the person who ingested it within seven days.

Jingyan soon realized that he cared more about his advisor than the life of Wei Zheng, demanding almost every hour that his people check on the condition of Mei Changsu. Lin Shu intially refused to let Jingyan enter his house (because he didn't want his illness to affect Jingayn mentally) but he barged in regardless. Upon hearing that Mei Changsu had ingested the pill and was set to die in seven days, he refuses to believe it. Luckily, Mei Changsu had swapped the Bingxu pill with a harmless placebo.

After Prince Yu's rebellion, Mei Changsu gets seriously ill. Jingyan watches over him and gives him some food. When one of his soldiers informs him that Mei Changsu condition is deteriorating, he stops his work and goes to watch over him.

At the end of the drama, Mei Changsu, now Lin Shu again, takes a pill to give him strength for three months, but killing him after. Even Jingyan and his other friends refused to let him go, he went anyways. Two years later, the war ends. Jingyan reads the death list over and over, but upon looking at the last name, he breaks down and starts crying. He names his new army after Lin Shu as a way to honor his dead friend.

Fanon
is one of the more popular ships within the Nirvana in Fire fandom. Fans usually ship them because they are childhood friends and because they both care for each other, even if they act cold at times. Whenever Mei Changsu was seriously ill, Jingyan seemed to always be worried for him. They also have somewhat contrasting personalities, as Lin Shu prefers to work in the shadows while Jingyan prefers to keep his work public. People who don't ship this romantically appreciate that they care for each other.

On A03, there are 1,078 romantic and 120 gen works for this pair.
