My System Is a Money-Guzzling Beast

What? The special medicine costs thousands? N-no... Just 500! You won't lose out, you won't get cheated, and it definitely won't cost you your house.

What? Your System gives you all sorts of stuff, and you're still not satisfied? If my System gets unhappy, it explodes and takes me with it. Worst of all, the experience it needs to level up is the balance in my bank account!!!
