Amagi Kurusu is a popular model making waves with her cool appearance.

I — Orimura Arata — am her best friend and work assistant. We've been together since elementary, middle, and high school, I accompany her to work, and we've always been the closest of friends.

「My dad remarried and I got a stepsister. And she's super cute, you know?」

「Hmm...」

「What's more, she even said she wants to marry me, which really put me in a bind.」

「Huuuuuuuuh.」

Ever since then, her behavior has been a bit strange. She's been unusually close, her gaze at me is odd, and I can't help but find her cute.

(Amagi is an irreplaceable best friend to me. I need to make sure I don't look at her in a strange way...)

(Tell *me* I'm cute, you idiot!! And what's this about a stepsister!? Marriage!? Arata is *mine*!!)

—This is the story of how the popular model and I became a couple.
