"Sister Siyu, what's wrong?"
It was Wang Zisu. He had just heard some strange noises inside and thought something had happened to Xia Siyu, so he asked out of concern.
Xia Siyu's mouth was covered, sealed tightly, not even a muffled "mmph" could escape. Her hands were also firmly grasped by Bo Yan, pressed against the door panel, immobile, and the same went for her legs.
Although she had trained in boxing before, and her strength was much more significant than that of the average frail female star, that was only in comparison with women. If a man wanted to overpower, it was very difficult for a woman to break free relying solely on her strength, especially since Bo Yan had also trained and was very strong.
But just because she couldn't break free didn't mean she couldn't seek help! Her hands and feet might have been restrained by Bo Yan, yet knocking on the door panel to make some noise was still possible.
