Deamon's Are Much Better (Sebastian X Male Reader)

What is a deamon?

Your P.O.V. (cat form)

I woke up on the sidewalk like I usually do after a long night of looking for food when I heard two people walk towards me.
"Young master what would you like in your tea today? I baught some more hearbs to make the tea fresher." What's tea? What's a master? What are hearbs??
"Today I will try some kind of green tea Sebastian" What's 'green tea'? What the hell is a Sebastian? Then the taller one that asked about the 'tea' stopped and sat (I say sat but we know he would never do that) down then picked me up. Then i noticed a slight scrape on my paw and meowed and winced in pain.
"Young master-"
"No put the cat down and let's go"
"Master. He is hurt we might as well help him"
"Ug. Fine but he's your responsibility"
"Yes I understand" then he carried me all the way back to what I guess is their house? Its fucking huge!!
"What shall I name you?" The tall one that asked about tea asked me looking down.
"Meow" I'm not in human form so I can't talk...
"Well I don't know if you can understand me or not but my name is Sebastian and i am a demon butler of the Phantomhive mansion" So his name is Sebastian? Hmm...
"I think I will name you Shebou" what? He just named me dead... Oh well its my first name and I'm so exited!
"*starts purring*"
"Do you like that name Shebou?" I guess I could get used to this.... But...what's..a, demon?
