Cool

You tease

The first thing to pop into my head as I started reading your story, is to wonder if anybody has talked to you about “show, don't tell”. I'd not yet read the part where you tell the readers Shiro and Allura are married. Why should the reader believe the two would get together simply because you the writer say they did?

The entire relationship, because there is no proper character development getting them to that point, feels forced. Character development isn't something a writer should ever skip over, but the characters are also terribly OoC. I'd like to say had they had the proper character development, they wouldn't be OoC, but unfortunately nobody really acts like this in real life. The first chapter practically sugar coats the experience of having a baby, and there is no sign of conflict. Everything is way to perfect, even when something imperfect like a Galra attack appears, as the attack just gets glossed over. The OoCness isn't slight either.

OoCness is always bad writing. Any changes to a characters personality needs to have a logical explanation even in an AU, which your story actually is not, at least not until what you wrote has been jossed. Two characters falling in love doesn't count as a logical explanation either, as the whole idea that two people will act out of character when they fall in love is a misconception. This said, keeping the characters IC is something that is learned by most writers. It would help if you utilized “show, don't tell” - there are some good essays out there that you can look up, but don't sugar coat things.
