No. The one with the female part is his blood son mole under the eye and the other one is a butchers son mole on the nose.
The author made them look like twins..
Yes they look like twins but they are not. They have different fathers and mothers. The one with the mole on his nose is the butchers son and he had his mother killed and kept him to raise as his heir since his original son was born “defective”. That’s why he’s so obsessed with getting him pregnant and producing an heir of his own blood. It’s explained when you read the whole story.
Um they are actually twins wtf?!
