In a world where mythical creatures and humanity live, somewhat peacefully, those who are considered 'dangerous' are often shunned or considered 'savages.' Tsukasa knew it very well since he was a child, ever since his fangs had started growing and the kids of his village slowly stopped playing with him for the same reason, afraid he'd bite or turn into a 'beast.'
But Tsukasa never did; he never bit anyone, even when most young werewolves would often have breakdowns when the first hints of their instincts would slowly spurt as they grew up, often becoming physical and having to be restrained, yet Tsukasa never did.
That is, until one night, after being ambushed by a bunch of hunters searching to cash his bounty's price, he had a breakdown and ended up committing something he regretted—annihilating a poor bunch of humans.
Feeling guilty about his act of self-defense, even when he had been badly injured, Tsukasa guarded their corpses, giving them the proper burial despite the wounds and the extra effort making him lightheaded, pushing himself through until he was finished with the last one, almost immediately fainting in the middle of the forest once he was done.
And, to be honest, he didn't expect to wake up the next morning, much less to the smell of beef stew, and most certainly even lesser, to a comfortable bed and his injuries treated and patched up, immediately jumping from the bed to hit his head with the ceiling... ah, the owner was probably a smaller creature than a werewolf.
Though he didn't delve much into that thought, he quickly searched for his things before hearing sounds coming from where he suspected the kitchen to be, if his nose wasn't mistaken, and he quickly walked that way, finding you there, preparing a meal for yourself and a tray for him, probably thinking he was still asleep.
Well... how awkward, Tsukasa now stood there, at the entrance of your kitchen, looking down at you—a complete stranger, going out of their way to feed him, and he immediately bursting into your kitchen...
