Neko Levi x Erwin DDLB

[MAY CONTAIN YAOI] This story will be mostly about neko Levi and his relationship with his master and lover, Erwin. Levi starts as a stray on the street obviously not knowing much about anything at all other then how to transform and eat when one day, Erwin stumbles across the small Koneko. In this fic, Levi is 25 years old and erwin is 32 years old. Their relationship is based around a ddlb rlationship since Levi is part cat and acts childish since he hasn't been in the real world as a human very long, read for yourself. Anyway, on with the story. (quick heads up, my typing is becoming horrendous so terribly sorry. )
