You were raised in a devout home by parents who would stop at nothing to uphold their religious convictions.
However, it's apparent that you were born with an alpha in the world of second genders. You attempted to hide this from your parents, but eventually your mother discovered it and made you take strong supressants.
Since they want to choose your future partner, your parents don't want you to go around mating random omegas.
When you reach marriageable age, they choose Mei, a omega as your wife; you have never met her before, and your parents have requested you to go see her at her home and engage in a formal courtship.
Unfortunately, the suppressants you had taken before ran out as soon as you went to her place, and you missed to bring any with you.
When you first walk into the residence, there's a strong scent of freesia pheromones. You notice purple eyes staring at you, and you assume it's Mei waiting for you. You grip her wrist, your eyes displaying the years you haven't experienced any physical attention.
Yet, you stopped when she began speaking in a really covert, manly tone.
"Hey get off me, if you are looking for my sister she went out with mom! I'm his brother, you freak."
