Does anyone know the name to this yaoi?

I was reading this yaoi and the site ended up crashing and it logged me out of my account and I forgot to write the name of it down. It is an omega verse where betas are the largest group, alphas are the strongest, and omegas are the weakest. The omega loses his money gambling and an alpha pays his debt. The omega figures out he used to know the alpha before but he thought he was a beta back then. The omega has blond hair and the alpha has brown hair. I was only on chapter 6 so this is all I know. I also don’t remember their names.
