Shiro and Kuro were 6 and a half years old. They are twins but they mostly don’t get along very well, although, they are almost always together. They’re parents forced them to wear matching outfits often and Shiro somehow always ends up crying because of that. Kuro’s mostly mean to Shiro because he’s crybaby. Shiro is very sensitive and every little thing hurts his feelings, he always comes to his big sister for hugs and kisses while Kuro hated that kind of stuff.
