She knew very well that the sound of the door opening meant that her parents had returned. If she tried to drag Hao Jian out to hide at this time, they probably wouldn't have found a hiding spot before her parents discovered them. In that case, not only would Hao Jian be unable to explain, but she would also have a hard time explaining to her parents.
Letting a boy stay over at her house in the middle of the night while her parents were away was something they certainly wouldn't overlook, even though they didn't usually discipline her much. They would undoubtedly demand a full explanation, and at that point, anything she said would be hard to justify.
In an instant, she acted completely on instinct, disregarding her embarrassment, and upon hearing the door open, she dashed into the bathroom, grabbing the handle and shutting the door quickly.
"This..." Hao Jian was completely dumbfounded.
