Just so you know, the alpha in this story has a brother who hates alphas, omegas in particular and betas. You can read the other story as well to know what happens to yohira. I won't spoil it but you might want to check out the other story as well. It's sort of intresting. Hopefully the butler finds a pair since he's a beta haha :9
Trigger warning for those who dislikes non-con skip this.
Also, this is pretty good manga of what happens a lot in society so putting this in Omegagaverse is good.
Your slice of life angst a/b/o story.
