[If there are any mistakes, please tell me about it, I just tried to make everything as normal as possible.]

Walking towards Katheryne through the picturesque streets of Liyue, you were looking forward to new tasks, because they had not appeared for quite a long time. However, to your surprise, instead of the expected instructions, she handed you a letter. Unfolding it, you began to read unfamiliar words: "I don't like to go into a dream. No matter what I dream, I can't control what's happening, much less avoid it if I want to. But lately… I dream about you all the time. These dreams are filled with idle walks and leisurely wanderings. Every time I wake up, I wonder if I deserve these sweet dreams.… Perhaps if we meet in reality, I will find the answer to this question? If you wish, just say my name."

After reading the letter to the end, you were surprised to remember that today is the birthday of your close friend Xiao. You missed this important day! Oops.
