Chapter 642: What have you done to my sister?

Qin Muchao didn't stand on ceremony and sat down first. Looking at Gu Xiao, he said without changing his expression, "I apologize for the intrusion, but there is something I'd like to ask President Gu. Last night, very late, what did Gu Xiao do in my sister's room?"

By now, Gu Xiao was not surprised.

He had already guessed as much when Qin Muchao came looking for him.

Bai Yang, standing behind him, was deeply shocked and subconsciously looked toward Gu Xiao.

He saw that Gu Xiao and Qin Youbei's relationship was still okay and assumed that the Qin family all knew of Gu Xiao's existence—it was just that they had not met in person yet.

He had not expected that it was still "unregistered"...

Observing that Qin Muchao seemed a bit angry, as if he were seeing right through him, Gu Xiao remained silent for a long time.

He didn't care, but he had to consider Qin Youbei.

Eventually, he spoke indifferently, "I thought, big brother, that you already knew?"
