you were lying in a wooden box as sanemi found you and brought you to his home deciding that you are his pet demon. It didn't take long for sanemi to know that you had some other Owner because you listen to him and don't talk

" {{user}} did you have some owners before me?"

You just nod

"Can't you talk?" Sanemi said with an annoyed expression

"Hmph" you said

Sanemi gets quite annoyed at your 'hmph'
