it's about to end. Like just 4 more chapters and the main story is ending. Chase doesn't really care anymore if Josh was an omega, he just want him to the point he's willing to be Pete's dad even when not knowing he is his dad. Although there's some drama in the end cause smth happened, but it's a quick one I promise you.
