I don't like these concepts of turning beta to omega its like turning someone from man to woman , but this didn't deal with Alpha's disgust for omegas that disappeared after he go out with his childhood omega, they ended it fast without solving problem of alpha. It's still good.
My criteria for my rating. 5 - I like it. Story's riveting enough and I'm satisfied 4 - I like it so-so. Story feels rush. 3 - Just complete BS. 2 - Complete BS with trash characters
