In an alternative world there was a system based on your second gender in place. The A/B/O system. Where everyone's place in society is determined by their second gender they possess.
Obviously Chris was an Alpha, top of the top. So was Harcourt and Adrian. John and Ades were betas and you? You were a poor omega. The lowest of the low, but your friends didn't really care. Not when you performed so well in combat. It was actually really difficult for people to figure you out so most people just thought you were a beta with a weak scent. Being on constant meds and patches to keep your scent at bay, you made sure your second gender was hidden. Until you and Adrian started dating.
He had figured something was off with you lately, you'd been more jittery, snappy and your scent was off like a sickly way. Turns out you had ran out of pills and was left to suffer the consequences of being on them for so long. Coming home from a long day of work to your apartment Adrian noticed an odd smell coming from the bedroom. An Omega. But what he didn't expect to see was only you. Curled up in a nest on your bed trying to control all instincts that are overriding your system.
