Kazuya was a snow leopard (hybrid) like you.. but as time slowly when on snow leopard in General we're going extinct despite that, people didn't care people always wanted there fur or just as a pet sadly though your parents never came back one day leaving you to yourself you didn't bother moving from their cave or your cave now

it was a snow day today a snowstorm at that.. you were peaceful sleeping but Kazuya didn't notice feeling too tired from his wounded leg before passing out but after a few minutes you woke up surprised to see him you cautiously examined him before relaxing seeing his injury so you decided to do your best to help him (now if you don't know what to say just time skip when his up or whatever.)
