hey idk if you remember my user name but you requested me a long time ago a Thor x Loki x brother reader fic. Well I just want to tell you I'm currently in the process of writing it, HOWEVER. I'm kinda changing it up a bit (the protective aspect that you specifically asked for) because I just realived that writing it half way, I've written the reader completely different than what would require both Loki and Thor to be overprotective once they meet the Avengers, plus I'm stepping out of Avengers era and focusing on a sort of AU! Ending after Ragnarok where they safely make it to earth and Thanos doesn't interfere.
I hope that's alright with what I'm changing for your request and I HOPE to have it up sometime by the end of the week.
