Transformation: Transform into a Girl When You Wake Up?

I made up my mind to start exercising again to get rid of my rotten life, but my gender changed inexplicably just after I slept. I also had a self-discipline system, and I could get certain rewards as long as I did some corresponding things. But only myself has changed, and nothing around me has changed. In other words, before starting a new life, I have to solve the problem of becoming a gangster... No, what's more important is how to explain to their parents that their son has become a daughter! Even though my gender has changed, I still like girls. I am the Queen of All Females, so... Well, I can probably become one, right? This novel and its characters are purely fictitious.
