I read this before but stop somewhere I can't remember where, but yeah, just scrolling to the latest chapter and I'm pretty lost... Can't someone tells me what's happening with the second couple, I don't think this story was an omegaverse to begin with, but what's happening with it?
Also does the main couple story ended? Don't spoil with what happened just tell me if it does or not. I'm gonna try to read this again...

Thanks in advance
