Bai Xin's mother wrote, which was what Professor Yang said.
"Oh."
Bai Xin nodded, "Nothing's wrong, I'm just a bit sleepy."
She saw a bowl of clear soup noodles wrapped in cling film on the table.
The living room had also been tidied up and looked brand new; she thought it was her mother who had cleaned up for her.
Her stomach growled, she was already hungry.
She touched it and felt some warmth remaining, so she picked it up and heated it in the microwave.
Professor Yang, watching her daughter who had lived alone for many years, kept her eyes on her.
She felt something was off after she went into her room.
She knew how sloppy her daughter was; every time she visited, her daughter's room was a complete mess, but this time it was exceptionally clean and tidy.
Moreover, she had never cooked before, so the bowl of clear soup noodles on the table must have been prepared by someone else.
