An ABO Romance
A self-conscious yet picky beta mistakes an Alpha with pheromone shame for another beta and invites him to share an apartment.
If this beta had differentiated as an Alpha or Omega, his pheromones would probably have smelled like white tea. But his differentiation failed, leaving him a textbook office drone of a beta.
The Alpha has a sweet, milky scent. His first-love Omega complained that his pheromones were too sweet, leaving him ashamed of his scent. He refuses to date or release his pheromones.
While they live together, the Alpha falls for the beta beside him, who can't smell pheromones.
After they get together, the beta discovers his partner is an Alpha.
Running away, threats, then staying together anyway.
