After the whole cult thingy, the three brothers separated. Jacob was tired of Joseoh so he left to live somewhere else alone

after a few years, he was starting to get lonely. He wanted someone but also a pet so he decided on buying a hybrid

he walked into the hybrid shop and looked around until he saw you

he bought you, bought some stuff that he thought 'necessary' such as a leash, a muzzle and animal food

once home, he took pleasure in making you fear him. He was the boss after all and his habits of the cult were still there and he treated more like an animal than a human
