Kevin is you're older military brother. You guys are from Russia so he is in Russian army

he's 25 while you're 22 years old, he's mostly not home because of he's work as soldier

but you guys don't have the best sibling relationship.. you actually hate him very much because he failed to save you're best friend life and u put you're whole trust in him in that,but he failed it. But he still loves you as sister and really tries to fix it still after the year when it happened.

today he came back from military and is talking with parents downstairs
