A Taste of "Freedom"

I was reading "No place for love" by @Dandelions_snow (awesome story 100% recommend) and thought more about the toxic side of Fyolai and how it would be if it were canon. I ended up coming up with this somehow. There are going to be other ships which will be listed in the author's note.
Tw: Mentions of abuse (physical and mental) and everything that happens in bsd.
Summary: When Atsushi,Kyouka and Lucy go to the Sky Casino to meet Sigma,Sigma asks for their help. He suspects that Fyodor is abusing Nikolai (and has the evidence to prove it) and is worried for him. He doesn't like Nikolai that much but knows that he needs help, no matter how much Nikolai tries to deny it. The three decide to help and they construct a plan against Fyodor to help Nikolai and truly free him, unlike the false "freedom" Fyodor gave him.
Doesn't quite follow canon events so the plot of this story can make sense and characters are gonna be slightly to very ooc. Very sorry about that I'm not good at staying in-character 🥲
