When he was in his first year of University, Nan Jateng had already sensed that yang manqin was acting strange, but he had not thought much of it at the time.
Later on, yang manqin's special treatment of Cha Qing Luo made him realize that something was wrong.
At that time, he only thought that yang manqin liked Cha Qing Luo and didn't know that she was a man.
After all, the Yang family and the Nan family were long-time friends. When Nan jiateng was young, he would often see Cha Qing Luo when she was young, and she was a girl.
He didn't think of her as a boy.
Later on, yang manqin stopped going to school and seemed to have disappeared from everyone's sight. The Yang family then told the public that she was sick.
At that time, Nan Jateng didn't suspect anything.
