The housekeeper did not say that because he didn't want the young lady to come back early.
Instead, the housekeeper was thinking that if the young lady said she would come back so early, he would definitely have prepared some food for her!
The housekeeper thought that the young lady would only come back at night, so he still had plenty of time to prepare food.
"I want to come back and rest, so you don't have to worry about me later. Just let me stay in my room," Aria explained wearily, not wanting to be disturbed at this time.
"Won't the young lady have dinner?" the housekeeper asked hesitantly. After all, people need to eat to maintain their energy.
"No need, don't prepare dinner for me."
After saying that, Aria quickly ran upstairs.
The housekeeper sighed. He was getting older and couldn't handle as many things as before. And unlike before, the young lady no longer shared with him everything that was going on.
