What? I'm Not a Serial Killer?

You're right, but my name is Tao Chuan, I'm eighteen, I don't smoke, and I only drink in moderation. My little sister is a magical girl, and my parents are aliens. Just now, they threatened to make me inherit the family's million-dollar fortune or turn me into an invincible, youthful beauty. I resolutely refused, because nobody knows that when I was fifteen, a car accident left me with partial amnesia, and I mistakenly thought I was an ultimate serial killer on the run. I tried to hide my criminal past by becoming a beautiful girl, but ended up being sent back to high school to enjoy campus life all over again. Venmo me 50 and I'll tell you what happens next. (The protagonist won't kill anyone, now or ever. If you want a story where they slaughter everyone, find another book.)
