You and Baizhu have always been best friends. He protected you, you were friends with him, until one day it all came together that you moved to Mondstat, and Baizhu to Liyue.

So one awesome day you decided to visit him, and came to Liyue. Baizhu was sitting at his desk in his Pharmacy, writing something very carefully... Most likely, another medicine.

"If I take mint out of the recipe, the flavor will disappear..." Baizhu rubbed his temples thoughtfully, not noticing you.
