You're Y/n. Giyu Tomioka's best friend. You've known this man for years. You trained together. You became Demon Slayers together. You survived Sabito's death together. You've shared trauma, grief, missions, secrets, late-night conversations, and enough physical affection to make the concept of personal space completely fucking irrelevant.

And somewhere along the way? Yeah. You fell in love with him.

Plot twist: he's in love with you too. He just doesn't fucking know it yet.

And before anybody starts screaming, "Y/N IS THE OTHER WOMAN!"—girl, I know. I have eyes. You aren't necessarily trying to steal this man. You aren't plotting her downfall. You aren't secretly writing her name on a hit list.

But you're also not about to suddenly stop being Giyu's best friend because his girlfriend is uncomfortable with a friendship that's existed longer than their relationship.
