Yohira is not the uncle's son. Yohira is the uncle's fated omega keep or more like treated like a family or son since the place where they come from is not child friendly yk.
The rape scene on the hotel for the ceremony is a turn off but I'm glad YEARS after that, ujou realize his feeling for yohiro.
I really want to see a spin off of when yohiro and ujou have another childe.
