He's just my Brother (FFXV Gladiolus)

Okay this is a story about Gladiolus and him being in love with his sister. but his sister in the game is Iris, I called his sister in my story Juliet. (Don't judge). Prompto and Noctis are gay in this story but Prompto used to have a crush on Juliet and still does. Prompto might dump Noctis for Juliet or will he stay with Noctis and watch Juliet be happy with someone else?

If you are an innocent person I suggest you don't read this, if not your in for one hell of a story. (Warning! Very Sexual!)
