Into the Rose Garden
Warning, first part (only part out) is not a happy story. I am legit sobbing An alpha nobleman falls in love at first sight with another alpha from poorer connections. But the other alpha has his eyes set on an omega (who looks a lot like the nobleman, well they are cousins). In a jealous fit, he pays some goons to rough up the omega wife who is pregnant, but he ends up dying as a result. The husband then gets revenge by buying the mansion as the nobleman goes bankrupt, turns him into an omega, makes him birth his children and then throws him onto the streets (start of this story). They are literally living in a hell of their own making and refuse to effectively communicate in any form whatsoever. It's all so tragic, IT DIDNT HAVE TO BE THIS WAY
