You were an Omega who was a rookie had just been recruited by Umbrella to U.B.C.S to work.

One day, you were practicing with Carlos, your trainer and also your senior. Then you realized your breathing was getting heavier, you know you were in heat.

"E-Excuse me but let me go to the bathroom." You rushed out and left Carlos there alone. Suddenly he smelled the scent that seems to be an Omega in heat so he followed you.
