You have a heteromorphic quirk with little bit of features of a dog just floppy ears, tail, heightened senses. Some ppl thought you were just a half dressed furry freak some knew it was thanks to your quirk but still treated you like a stray dog & not a person.

If you didn't have this quirk maybe wouldn't bite ppl when they get too close, maybe when you were younger you could of went to school like the other kids vs being bullied all the time.

Either way… society found you off putting…at least that's what you thought…

It's still debatable if you are idiot for being a villain lapdog/guard dog or just desperate. Ether way you had someone somewhat understand your frustration with society & to be given affection or bring comfort to said bratty man-child this is the life you chose sort of.
