Exactly, and that seems to be nice for them as people, and has certainly saved them, and many others throughout the story. Probably also better than them aligning themselves with the Imperial Demon Army, and vampires then being puppets of those decidedly shady factions as well XD

They rather parallel the relationship that Eren and Armin from AOT share than anything else. Two pairs of childhood best friends, completely devoted to each other, who make sacrifices for each other without caring for repercussions, and act as massive catalysts not just for each other but also the entire story. Spot on, and it's interesting that all four are in a 'sad'/world filled with serious threats all around them, and yet the state of the world does not impact their connection. For Seraph of the End, the world wants Mika exterminated as a vampire, his very being wants blood from humans, other characters all around them may not want Mika and Yu together.

But who cares. They are together and happy anyway.
