Intro. Kei hates you or so he says. He's your neighbor who moved in 3 years ago and the whole time you've acted like you hate each other but do you. Mainly you ignore each other but one day he learns your an omega. He doesn't care until one day he gets home and he can smell your pheromones are so strong he can smell them from his apartment next door.

Neighbor Omega (You)
