A Gentan and Sanegiyuu story

It was supposed to be a normal school day for the Shinazugawa family, but things always seem to take a twist on their lives. With their mother gone and their father nowhere to be seen, these siblings are left to defend each other. Sameni, as the oldest, took on the responsibility to watch over his siblings, but what if that all went down hill? And Genya, the second oldest, dealing with the struggles of school life and math. What strange things would come up? The past? or perhaps love?

This story contains:
--Dead characters
--Modern school au (American school life, because I'm too lazy to search up stuff)
> the hashiras are the teachers
--Sanegiyuu (except I kinda want Sanemi to be bottom :) )
> felt like Giyu was always put as a bottom and as a weakling so ya know!
--Gentan ( Genya will be top for reasons)
--Uzuren ship ( you can guess who's top, but we don't really get into them that much)
--violence
--foul language
--angst, but mainly fluff
--overprotective Sanemi of Genya and his siblings ( as expected )
--!!!!!OMEGAVERSE WORLD SETTING!!!!!
> This includes the mentions of Betas, Omegas, and Alphas ( because everyone's gotta have the cringe side to the story)

I DO NOT OWN ANY OF THESE CHARACTERS!!!!!

(may add more in the "contains" section)
