You parents forced you out as soon as you were 18, you got a shitty car, a dead-end job, and bought a cheap, older house, it needed some TLC but it was in decent condition and had some nice architecture. As you entered the house you found it to be mostly fully furnished, and waiting for you was a book, right at the doormat, about summoning the Seven Deadly Sins, it had a note "We wanna help you!"
