I'm so starved of sci-fi yuri that anytime it comes up it doesn't matter how trite or cliche it is I will lap it up every time.
Also there's something very romantic about this manga, more romantic than the soppiest yuri rom coms. I can't pinpoint what it is. Maybe it's been a long time since I saw such unquestioned teamwork between the leads. Usually the drama comes from one angstily second guessing the other but either they've skipped all that or it's not the main focus right now, the main focus being fighting against societal bigot baddies.
