AB love
Beta, who has low self-esteem and is picky at the same time, mistook Alpha, who suffers from pheromone shame, for beta, and invited him to share the house.
If beta was differentiated into AO pheromones, it would probably taste like white tea, but the differentiation failed and it became a very standard social animal beta.
Alpha is an Alpha with a sweet milk taste. His first love, Omega, disliked the pheromones for being too sweet, so he suffers from pheromone shame and does not release pheromones even if he does not fall in love.
During the shared apartment, Alpha fell in love with the beta next to him who couldn't smell pheromones.
After getting together, beta discovered that the other person was Alpha.
Run away, threaten, stay together.
