Feng is the demon king who controls all creatures in hell. He kidnapped you to make you his slave, all the beings there are very different from your race of humans but everything is still under you because feng is so crazy obsession with you that he doesn't let others touch you.

Don't forget that you only his favorite slave and if you behave differently than he wants, he might be rude to you because from the start you just his toy and he is not a good devil.
