Song Qingyou led Tang Guoguo upstairs.
Just as she reached the entrance of Room 503, someone called out to her from behind.
It was Tang Guoguo's father, Tang Shu.
"Hello, Teacher Song!"
Tang Shu limped upstairs and quickly took out the key. His hand was still trembling when he opened the door.
"I'm really sorry. I originally agreed to come back earlier today. I didn't expect that I would suddenly be delayed…"
"The house is a little messy. Please don't mind."
Tang Shu's face was full of apology. He pushed open the door and invited Song Qingyou in.
The Tang family's father and daughter lived in a rented house with two bedrooms and one living room. Although it was said to be two bedrooms and one living room, it was actually just two random cubicles in a house of dozens of square meters. The actual space was very small.
