Got a Secret can you Keep it?

Keith's father always had two lessons he had taught Keith young, Don't tell anyone about his second gender and don't trust anyone with his secret. But now Keith's in space and dealing with more than his father could've ever predicted.

Keith was born an omega, something unheard of for humans. Bouncing around the foster care system left his heart jagged and his ability to trust anyone broken. But his friend Shiro had started to break those walls down, before he was lost in the Kerberos mission.

After a long series of adventures leaves Keith in space with 4 new friends, he's left alone to struggle in finding his place in their pack and with his own identity. Meanwhile, his own feelings are left to fester as he watches Shiro and Lance become a couple, something he wants a part of.

How can Keith overcome all the struggles without breaking? Will he be able to confess his feelings and get his men? Or will Keith put his team before himself all over again and let his own desires be ignored like always?
