Hello, its me again

I'm trying to re-organize my files because some of my books gone

and here another books I can't remember..
It's series of paranormal books (werewolf?)
about two pack, one pack was in a remote place and very traditional/old-fashioned. The other is more modern and has a school/academy for werewolves in their area.
The academy had separate dorms between the Alpha and Omega. In this academy, the Alpha and Omega learn to perform their duty, but they also can looking for potential mates in there.
I can't remember much the books itself

But I think the leader of traditional pack send his children to go to academy there. Later one of his children will mate with son of the pack leader there and forge an alliance between the two packs.
if I remember correctly, in one book tells the story of one of the students (omega?) of the academy were tortured and kick out from his pack because of returning home without mate. He was rescued and he works in (in kitchen?)the main house of the modern pack. One of the children (alpha?) of the pack leader fell in love with him when he saw him standing under the moonlight in his wolf form. Because he (alpha?) didn't know who the figure behind the gorgeous wolf, he is always looking forward to time to see the beautiful wolves show up again and find out who has stolen his heart.
This only can I remember, I don't know for sure if this is true in one series or not

but I hope there is someone who can help me to find this series

Thank you in advance,
Dee
