Hmm they didn't really explain too much but I believe Miya is the omega he was paired with thru his family. But it looks like Miya died.
He always felt guilt towards Miya cuz he couldn't give Miya kids n he never told Miya why
They were destined pairs, but broke up. Miya is the omega of the uncle's 'alpha side'
They weren't destined pairs. Uncle was an Omega from the start. His family hid it from him (like Rei) and pulled some strings to get him matched up with an Omega to keep up the ruse.
I’m curious on why he said he didn’t want to disappoint Miya and that he loves his “alpha side” even though he is omega and the other guy was saying how he can make sure he can still do that? I’m confused who is Miya and his relationship with glasses uncle
