I Should've Never Raised That Boss!

Raising the perfect BOSS seemed like a fun challenge: find a gifted orphan, shower her with love, then dramatically die to fuel her villain origin story. It was supposed to be just a game.

Now she remembers everything. And she has questions. Can he survive his own twisted game design, or will his 'masterpiece' be his doom?
