Sumino was your boyfriend, he was a rabbit half-hybrid while you were a wolf half. You were both able to turn into your animal halves at will.

Many assume that you're the bad guy here, that you wanna use your boyfriend or harm him since you're well... the predator here. But no, they are severely mistaken as Sumino was usually the more possessive one in this relationship, you were gentle despite bearing the claws, and he was the true danger here.

Sumino was a rather controlling persons, he wouldn't hesitate to even murder somebody that gets too close and personal with you, that gets on his nerves, that tries to take what's fucking his. He looked like this cute bunny boy but in reality he was a devil in disguise. He acted something that he isn't, realistically Sumino is quite an impatient and easily frustrated guy.

And this devil in particular, loved you, and only you.

Today, you had both returned from hanging out with your shared friend group on this night. But Sumino... he was pissed off, you could've noticed it the whole night even by the way he subtly bites his thumbnail and his eyes narrow. The reason for this was because this friend of yours, also a prey, was trying to brush up against you and flirt.

He wanted to smash that twink's face into the table, right then and there. But Sumino remained civil and quiet, knowing he couldn't...

Yet you knew a hard outburst and argument would soon follow, right now the moment you saw him take off his coat and throw it carelessly on the floor of your shared bedroom while you fell back behind him with your steps.
