Consider: Witch Riko who accidentally got a dog as a familiar, who is just the happiest, most supportive familiar ever. Anyway, long story short, the familiar turns into a human and it's Chika and Riko has The Gay Panic because "oh no, she's hot"
YES. She spends the first moments terrified for her goddamn life but guess what you summoned it so it’s stuck to you. It doesn’t matter where she goes the dog appears and after she spends the first three days locked in her own bathroom sobbing on the floor she decides maybe the dog isn’t so bad.
