My secret Mate (Vkook)

Where a omega finds his mate but doesn't tell anybody about it they both except each other. But his mate is son of alpha and Luna in a different pack so, he will become a luna when they fully bond.

The omegas hyungs worried that he won't find his mate and try to hooked him up with alpha who were mate less.

What will happen if the omega tells them his going to be luna with his mate. Will they be mad him for not telling them or will they be happy and forgive???
