Why Did the Promised Knight Turn into a Witch?

My name is Ning Zhuo, male, and I like women. When I was called to the door by the system, I thought I had obtained Long Aotian's script and would reach the pinnacle of my life. As a result, the first day of time travel—— Gender, female, voice, cool lady, figure, bumpy. Ning Zhuo: "??? I'm here to be a righteous knight, not a righteous knight!" System: "This is based on the fact that you only play the heroine when playing the game, and only draw female characters when drawing cards. It is customized and generated for your preferences!" "Is that the same thing?" Fortunately, I found out that I could return to the original world after death, and I would still be a man, which made me feel a little better. But why, I feel like my skin has become whiter, my voice has become thinner, and my body has even become smaller? Can anyone tell me what's going on? Damn system, it must be your fault! ! !
