I’m trying to find a Jegulus fic where Evan’s obsessed with Regulus!

I'm a hundred percent sure that was a jegulus fic (because I don't read any other ships these days)

Evan and regulus were related through druella, but evan was so obsessed with reg. Every time someone mentioned something like, "You're cousins," he immediately denied it, saying, "We're not blood-related cousins," because he fancied reg...

Meanwhile, regulus was definitely obsessed with james.
Does anyone know the name of the fic?!
