The situation is actually quite simple.
Yu Yao just wanted to find Bu Tingyue, to go to her room, but the Shopkeeper was definitely going to prevent that, because Bu Tingyue had just instructed that she didn't want to be disturbed during a small reunion with her brother. They hadn't seen each other for so many years, both were family, so naturally, they would have a lot to talk about.
Yu Yao frowned and said to the door:
"What are you afraid of? Is it Tingyue who told you to stop me from going in? How could a girl as broad-minded as her do something like that?"
"Besides, Tingyue and I are friends, we have so many friends between us, our friendship is one that has been through life and death together. If she knew I was here, she would definitely let me in; how could she let her friend stand outside and wait? Otherwise, is she still a part of the Celestial Craft Workshop?"
