Probably still the best "omegaverse" story out there!! As it also happens to be one of the very first. I love it for its wide variety of couples and interesting story. Ironically I don't like the main couple all that much but the side couples make up for that. Particularly Yonekuni x Shiro , Kumakashi x Joshua, and David x Maximillian. I'm also super interested in Shinobu and Vulnera's story.
