The small villa.
Gu Si was gaming with Jiangsui.
After finishing one round, Gu Si looked at the time. "It's almost 10pm, why isn't my sis home yet?"
"Perhaps Professor Yang has a lot of things to teach them," Jiangsui answered. He thought for a while and suggested, "Why don't we send her a message and ask her?"
"Sure." Gu Si left the game and entered WeChat.
While he was typing the message, an incoming call notification popped up on screen. It was a call from Bai Sui.
Yu Mufeng glanced over and said casually, "Is Sister Mang going to stay over at the hotel tonight because they will end late?"
Gu Si raised his eyebrows. "I don't know."
With that, he accepted the call.
Bai Sui said something and Gu Si's face went from nonchalant to sullen immediately.
Yu Mufeng sensed that something was wrong and he looked at Gu Si.
"I got it," Gu Si said. Then, he hung up and stood with the phone firmly in his hand.
