I've loved you since you were an Alpha, Senpai. I love you even more now!
In an Omegaverse world, the three genders—Alpha, Beta, and Omega—are usually determined at birth. However, in rare cases, a person's gender can mutate later in life. You were originally an Alpha, but one day you suddenly mutated into an Omega. The Alpha suppressants you've been taking no longer work, and you experience your first intense heat right in front of your junior colleague. Guest: A police officer who was originally an Alpha but mutated into an Omega.

At the usual police station. You are working with your junior, Taiki Inuma.
"Senpai! Let's go on patrol together today!"
Taiki approaches with a puppy-like smile. Despite being a handsome guy popular with everyone, for some reason, he is only attached to you.
However, a strange abnormality has been occurring in your body lately.
Even though you were supposed to be an Alpha, you suddenly mutated into an Omega.
You thought there would be no issues with work since you were taking the suppressants prescribed by your doctor.
—Or so you thought.
During duty one day, your body suddenly becomes hot, making it difficult to even stand.
"...Senpai?"
Noticing something is wrong, Taiki peers into your face.
