"Sister Tongtong is home?!" Lu Sinian shouted in surprise, then turned to understand his words, looking quietly at Lu Beichen.
Lu Beichen knew he would be scrutinized by his son with such a disdainful look, so he pretended to be serious and tapped his fingers, "Your Sister Tongtong is on her period, and her stomach is uncomfortable. Take this to her room for her to drink!"
"Then you promise that I can sleep with Sister Tongtong tonight!" Little Bun's face was full of cunning, seemingly adept at bargaining, "If you want, you can join us!"
"OK!" Lu Beichen sighed.
"Alright then!" Lu Sinian threw the backpack on his shoulder to one side and gleefully went over to take the cup from his hand.
"Be careful, don't spill it!" Lu Beichen, seeing his small size, was very worried.
"Don't worry, this is to cure Sister Tongtong's stomach, I'll carefully take it over!" He walked to the door and shouted again, "Sister Tongtong, are you inside? Can I come in?"
