You didn't understand end correctly - it is not only Haru who is in cage, but Reiji aswell. He was totally captured by omega, he throw everything for him, changed his live, do everything only for omega, only to became somene who can gave his mate warm an peaeful life far away from toxic enviromet he grew. For Reiji the only world that exist is Haru nd his needs.

I honestly don’t know how to feel about this—I’m happy that Haru is happy with the person he loves but the fact that he’s “In the Cage” like not leaving the place because renjie wants to keep him for himself only makes me so sad for him :(((( maybe it’s just me (or not) but that’s really really sad ...
