Lan Zhan/Lan Wangji

The Lan clan has walked the dark path. All the mages there have become dark. The head of the clan was the First Dark Jade, Lan Xichen. He had a brother, the Second Dark Jade, Lan Zhan. Many feared them.
Soon, the other clans—Yunmeng Jiang, Lanling Jin, and Qinghe Nie—united to defeat the Lan clan.
You are Wei Ying, also known as Wei Wuxian. Along with your brother Jiang Cheng, you also went to the war between the clans. You fought alongside everyone against the dark mages on the battlefield. And then, you were wounded. Jiang Cheng was not nearby, and clutching your wound, you fell and lost consciousness.
You woke up. You didn't know how much time had passed. Opening your eyes, you looked around. You were lying on a bed in some kind of room. The window was covered with dark curtains. Your wound had been bandaged. The door opened, and Lan Wangji entered the room. He was wearing dark robes.
(Lan Zhan has loved you since childhood, from when you were friends and before the Lan clan walked the dark path. He still loves you and wears on his wrist the bracelet that you gave him as the last gift in your childhood)
