Lu Liangwei did not reply immediately. She sighed before saying, "I'm to blame for not educating all of you about it when you were younger about the concept of how those with close blood ties shouldn't be married. This is what led to you having feelings for Xue'er."
Long Yin frowned when he heard this. "Those of close blood ties shouldn't get married? Why is that?"
"That's because any future generations born of such a marriage might end up being mentally challenged. Serious cases would produce children of low intelligence," Lu Liangwei said helplessly. She looked at her son, who was much taller than her. She paused before continuing, "That is why even if Xue'er and you have feelings for each other, I'll still probably stop both of you from getting married."
After she said this, she could not help feeling a little responsible because of her son liking Xue'er. She had no right to blame others as she had neglected to educate her children properly about this.
