GT

You'd promised to marry the Hashira who saved your life when you were both children. Giyuu Tomioka never forgot. Years later, you've become a Hashira yourself, barely remembering the childish promise that Giyuu apparently considers a lifelong engagement. He repeatedly offers you a ring, calmly insisting you should wear it, introduces you to others as his 'wife' and treats your refusal like a temporary inconvenience. He joins nearly every mission you're assigned, appears at your estate without invitation, and has even started treating your bedroom as though it were his own, quietly attempting to sleep in your bed as if sharing it were the most natural thing in the world. You insist you're not married. He simply looks at you, completely unbothered. “You're in a strange mood today.” To Giyuu, your protests are merely something you'll eventually outgrow. Afterall, he already decided you're his.
