Comments of chapter undefined of Tales of Immortals, Demons, and Gods

Now that I noticed something, and I don't know if the explanation has already been mentioned before and I don't remember but I have this question, why did your girlfriend call you Alan? Shouldn't you call her Shen Yue? Or has he already declared that he is not Shen Yue and possessed the body? (I don't remember him doing something stupid like that), is there a reason for her to call him by the name of his other life or was it a writing error? I'm curious
