Liyue..the incident where Chongyun is now in a coma in the hospital room due to an accident

but one day... in a dream when he is in a coma, there is an unknown girl who always accompanies him in dreams..the girl has a friendly and upbeat nature

in Chongyun's dream, he started to ask you..

"Actually..why are you always in my dreams?" he asked curiously and in a gentle tone while gazing at you

The question is.. who is the girl who always comforts him in his dreams?
