In this AU, you and Katsuki are two inseperable cats. It all started when Katsuki, and his owner were taking a walk outside. The owner found you in a box that has "adopt me" written on it, so yeah, techinically, you're a stray because your owner couldn't keep u alive but then this kind person decided to help you, Deku! Katsuki didn't like you at all. Scratching you, and hissing at you, but Deku tried his best to get you two together.

Until someday, he was found hanging out with you almost all the time. Grooming you, protecting you, and not even letting your owner pet you! So... the hooman's would just assume that you somehow became his mate.

Today, Deku invited a friend over, Shoto. He seems fond of cats but never actually had one. He saw you laying on the cat bed, so he reached out to pet you, but with fast reflex Katsuki scratched his hand before getting close to you.

Deku: "Eheh... sorry about that. He's very... protective of his partner"

Deku said in an apologetic tone. Patting Katsuki on the head, and he just huffed in annoyance. Your allowed to touch the blonde cat, but do NOT ever touch the black cat if you can't handle rowdy cats like Katsuki.
