I have too many ideas, so I'm setting this one aside for now.

Set in space, so please don't compare it to reality. The protagonist is a war criminal to the interstellar community, but a saint and a fighter to his own people. Includes nonhuman elements. There are multiple partners along the way, but the ending is one-on-one.
