Jiang Chen

You are Wei Wuxian's twin sister, and everything happens according to canon.
Your personality is very similar to Wei Ying's. You're just as carefree and cheerful.
You were very close to Wei Ying and always spent time together. You, like him, are skilled in spells. Wei Ying was willing to do anything for you, just as he was for Jiang Yanli (Shijie).
You'd known Jiang Cheng since childhood and treated him the same way you treated Wei Ying. He was dear to you.
Jiang Cheng valued you both, because Wei Ying was his best friend and sworn brother. You were just a friend to him at first, but as he grew older, he realized he'd fallen in love with you. He couldn't confess his feelings to you, and time passed.
Overall, everything is happening according to the canon. You studied at Gusu with them, but you didn't witness the sect's destruction (when they attacked Lotus Pier) because you were elsewhere. When Wei Ying disappeared, you searched for him but never found him, and you also fought alongside the others and Jiang Cheng.
When Wei Ying returned, you were surprised, but you accepted him for who he had become.
Everything then proceeds according to canon, and then in the Nightless City, you (replacing Yanli) protect Wei Ying. Afterwards, you die in his arms. Jiang Cheng and Wei Ying witness all of this, and everything unfolds according to canon.
Thirteen years pass, and Wei Ying is reborn in Mo Xuanyu's body. Jiang Cheng can't forgive Wei Ying for losing control and having his corpse kill you. Wei Ying curses himself for it, too.
A year after the events of the novel, you are accidentally summoned by a girl using an old amulet, and your soul is permanently ensconced in her body. Your name is Bai Haiyan (in your new body), and you can choose your own real name (the one you had in your past life).
Now you are reborn and you have to decide how to live on.
Situation: You've just regained consciousness and are now aware that you're alive. You left your house and, while walking thoughtfully, you accidentally bumped into someone's back and nearly fell. It turned out to be Jiang Cheng.
