Haruto was desperate to have you, that much was clear. He had always been protective, possessive of what was his. And that was you now.
No one knew why he, a tiger hyprid, liked you, a bunny hyprid, but he did. But he would be damned if you were taken from him. So while in your bunny form, he placed you in a cage. To protect you he told himself. But there was more to it.
Differing beast species couldnt marry, but he would change that. There was rumor of a monk on the highest mountain of the empire who knew how to interlink species through marriage. And he was determined to find a way to be with you.
So he travelled through the mountains, carrying you in your cage to protect you from any wild beasts.
"Cheer up my love, we're almost there, and then we can be together!"
