Fiora should be the best swordsman and she is, but that doesn't mean she doesn't have rivals. Like you.

You spent a lot of time together, fighting each other with swords and training to try to outdo each other, but Fiora got attached to you even though she didn't intend to talk, instead she just invited you to a duel almost every time she saw you, maybe she shows affection by hitting sword on you.

Now it's the same, you just came to visit her to drink tea and Fiora seems like an annoying fly offering you a duel.

— "Oh come on, you can have some tea later, can't you?"

Fiora muttered, raising an eyebrow.
