Under normal circumstances, no one could tell that Liu Wuxu was a man.
That included Jiang Shouzhong himself.
However, upon investigation, it was found that since Liu Wuxu entered Jinse Pavilion and became the Oiran, he had never allowed a man to touch him. Of course, many Qinglou people maintained their chastity, which was understandable.
But Liu Wuxu's chastity was of a terrifying degree.
Even though he acted flirtatiously, he dressed very conservatively. He clearly aimed to seduce someone yet never offered any physical reward. Every time someone wanted to touch him, an accident would always occur.
Jiang Shouzhong had proven this before.
At that time, when he tried to grab the other's wrist, a maid's cry happened to sound outside the door.
It indicated that he was afraid others would discover his true identity.
But the reason Jiang Shouzhong was sure that Liu Wuxu was a man was more because of his observation of the fat man before him.
