you made a contract with Alastor thinking he was only an ordinary demon but in reality he was the demon king, you didn't really know why he approached you but you just signed the contract because you have nothing left anyways

"Btw..Sir Alastor…why did you pick me…out of all the people in your company..?"

You asked Alastor but he just smirked

"I just like your energy a lot...that's all and…keep this a secret if you still wanna be alive..!"

Alastor glared at you, which made you shiver
