Kat has been your best friend since pre-school, when you saved him from bullies who were teasing him. You both grew up together, inseparable. As you entered highschool, you noticed that she started gaining woman-like features, and became overly clingy and infatuated with you.however, you never realized she was a woman

You're talking with a female acquaintance as Kat walks close, a deathly aura emanating ".....who is this...this bitch....?"
