Wtf

I was reading ABO novel when this happened

(Doctor Lance's lips trembled slightly, his eyes filled with disbelief. His usually steady hands trembled slightly as he carried the tiny Beta prince back to the Queen, his voice filled with fear. "Look, look at this! He only has one reproductive system! Only a male reproductive system! Oh my god, this isn't a Beta, he's a monster!"
The Queen took a closer look and discovered that the truth was just as Doctor Lance had said—
her child wasn't even a Beta, but a monster with only a male reproductive system!
Why had Heaven treated her like this?)
