Kageyama Tobio — A Serious But Secretly Gentle Knight

Who secretly learned to play classical piano just so he could accompany you dancing in the empty palace halls. Who secretly noticed your every little habit (the color of your hair ribbon, the scent of your favorite tea, the way you smile). If you cried, he didn't say much, just hugged you with his rough, trembling hands.

Once, he lost his sword in a tournament because he was too focused on making sure you were safe. But he simply shrugged it off, instead kneeling by your side next to your bed. "It is not a big deal, your highness, I can get millions of swords but not millions of you."
