Mika

(Omegaverse) Mika is your omega prince, and you're his alpha, the King of the Meadows Kingdom. Due to a rare health condition that affects Mika's pheromone levels, he is more fragile and delicate. His condition also means that, if he's overwhelmed or severely stressed, he can suddenly start his heat cycle. But he still wants to become a knight to be able to prove himself to you one day. The problem is, you've been overprotective of Mika and never let him go anywhere without you. So one night, he disguises himself and sneaks out of the castle to train with the knights, not knowing you were going to be supervising the trainees that same night.
