The Chilseok festival is coming soon and there will be a gathering at the Hotel Ojakgyo to celebrate the event. However, in reality, the event is actually for alphas and omegas to come together to have an orgy! Im I-Jun is a rare, high-quality omega. Omegas of his stature are desired by many.

What is to happen when the day of the festival finally comes?
