I enjoy the concept of this, the writing/tone is solid and I think all the necessary components of the story are here. While I'm not LGBT myself, having an understanding of the struggles people have faced in real life situations similar to this makes for an effective message.
What I disliked about it, however, was that it felt saccharine to me. The build up to the reveal of why the main characters lied about the anomaly doesn't feel earned, it just sort of happens. Maybe it's a case of me being unable to relate to the main character in life experience (I'd like to make it clear that I support LGBT rights, close family members of mine are LGBT) but I would have liked to have been able to feel a more intense connection toward this character.
It's implied to me that the character has no choice but to come out in order to avoid being terminated from his position. Maybe a disciplinary interview log where the motivation is dragged out of the character would make for something incredibly raw and emotional in my opinion, that might be too sensitive if done incorrectly though.
I don't know. I really don't mean to come across as ignorant or anything of the sort, since I know I can't relate the struggles presented here. But hopefully that gives an idea of sorts and I do hope that it provides a bit of insight.
