I think you're mixing it up/ with another story? Probably Kiss me Liar?
As I said, Josh still works as his bodyguard after the main story.
He tells him the truth at the end of the main story.

In the epilogue Josh works somewhere else, and comes home to his family -Chase and the kids.
In the side stories that continue the plot of the main story you see Josh two times at home. One time when he wants to introduce Chase to his mother and sister. And another time when Chase stops using his meds, and the doctor thinks it's better to separate for some time, because of his omega pheromones. But Grayson get's him, when Chase goes into rut.

I’m not talking about the end I know they end up together and chaze learns about the omega thing after he’s being kidnapped. They stay body guards that I know because of the side stories. But normally in the main story if I remember right Josh stops working for a while and comes back after chase goes to his house to take him back as his bodyguards and that’s when he discovers Peter and gets the idea Josh has a wife he’s cheating on with him

He finds out about Pete when he overhears Josh and Isaac talk irrc.
Josh sometimes goes to his mom's home to check on Pete, takes a few hours - a day off. He also meets Dane one time and another time runs into Yeonwoo. He never stopped working and he never ran away during the story.
Chase never went to Josh's house in the main story. He only went there in the side stories, when Josh wanted to introduce him as his partner.
We still got ages till its all sorted, He’s gonna find out he has a kid and think he’ll think hes married with a girl, then he finds out he’s a omega, get jealous, angst, omega runs away, chase arch then we get happy ending. Bro thats like ages away
