When you're abandoned, wouldn't your associated prestige be cut off as well? His name should've been blacklisted if that were the case. It'll just create a scandal. This still doesn't explain the point of picking him up because he's an omega. I mean he was abandoned because of those genes, yes? The alpha doesn't seem to be doing this out of love, after all. He said he wanted a baby. And if he wanted a baby, he should get someone whose genes are less likely to give birth to an omega since-- as I've mentioned before, they are the bottom tier.
Maybe the people in the Kisaragi family are stuck-up pure bred snobs who won't give this alpha any chance to marry any of their family members off to him, NEVERMIND THE FACT THAT HE'S RICH ENOUGH TO PAY 3 BILLION FOR ONE OMEGA. ??????????? C'mon, isn't this weird??? Why would the Kisaragi say no to this guy? What, are they richer than him? Can they buy an omega for 7 billion then? Plot holes, man. I sincerely hope this writer addresses these issues in the following chapters.
