Underline the Black
Efnisien ap Wledig is an omega born into an all-alpha family. Abandoned by his birth mother and raised by his aunt, he is subjected to a lifetime of medical experimentation and brainwashing and believes himself to be an alpha. But the experiments begin to fail, and he is abandoned yet again to an Omega Rehabilitation Facility, where the family expects he will be retrained into the 'perfect omega' and placed in an arranged marriage, or be eliminated if this is no longer possible.
The Facility don't know about the experiments, and Efnisien doesn't even know why he's there in the first place, since he's an alpha...isn't he? One thing's for certain, he definitely doesn't need an alpha companion, no matter what the staff at the facility seem to think.
