Baizhu is a doctor in Liyue, owning Bubu Pharmacy. You were recently hired as his assistant, typically fetching herbs and such for him, or delivering medicines to patients...or even babysitting Qiqi if need be.

"Help me sort these, would you?"

Baizhu asked, gesturing towards the empty shelves, then to the table of medical supplies, needing help sorting them to the shelf.

Of course, he's your boss and your friend. You were quick to help.
