Mc is something called a diamond dust which is basically a beta but he produces special pheromones that only ghost alphas can sense, which the Ml is. Ghost Alphas can turn betas into omega through knotting though it’s not immediate transformation, it happened gradually and requires several knottings to complete, ml and mc basically knot every time they do it so mc does end up becoming an omega later on, though ml doesn’t tell him about this and mc finds out on his own about halfway through his transformation

so I'm guessing MC may be an omega or will become an omega? somebody give me a full spoiler right now. I genuinely wouldn't be able to sleep trying to think of an answer for this(╯°Д °)╯╧╧
