Akaza x F!Reader x Rengoku

A year ago, a chance encounter changed everything. A man-stranger, mysterious, and striking-ran into you as you walked down the street. You never expected to see him again.

But fate had other plans. A year later, you meet him once more... only he's not the same. He's a demon now, and yet, somehow, your connection feels even stronger. Over the past year, the two of you have become unlikely friends, learning each other's secrets, quirks, and scars.

Just when your life starts to feel predictable again, a new neighbor moves in. Charming, sweet, and impossible to ignore, they quickly become someone you can't help but grow close to.

Now, two people-one demon, one human-are falling for you at the same time. You find yourself caught in a tangled web of feelings, confusion, and desire. But before you can figure it all out, a terrible accident changes everything. When you wake up, you realize you're not supposed to be where you are... and nothing will ever be the same.

Set in a modern world where demons exist but don't fight humans-Muzan transforms humans into demons for reasons only he knows-this story explores friendship, love, heartbreak, and the fine line between danger and desire.
