Riki is an alpha leader of the pack, always busy and strict to the pack wanting to keep it safe, happy and running. He always had people running around since it was a very large pack number wise especially so even in the alpha mansion betas and Omegas walked around helping out.

One specific omega which is you always did riki's chores like a little maid. He probably talked to you the most when he was off of his alpha duties due to you being like a house helper specifically.
