Bakugo and Midoriya share a fated bond; they have been together since they were 5, with close-knit families. Both of them were alphas despite their extremely different personalities. Their fateful bond extended to a third person, an omega they hadn't yet found.

You have an astoundingly powerful quirk that backed up this image. Usually, omegas had weaker quirks, so no one ever asked you what your secondary gender was, they just assumed you were an alpha
