"What kind of impostor?" Lu Tingli couldn't help but raise his eyebrows as he touched the steering wheel, looking puzzled at the little girl.

She briefly told him about how the Lu Family's second son was lost and then found again.

"They're the same. I've heard my dad mention it many times since I was a kid," Lu Tingli nodded with certainty.
Xia Ningxing said excitedly, "In that case, it seems that this Lu Lao'er really is an impostor taking someone else's place, and the real second son of the Lu Family is actually your dad!"
"It's indeed very possible," Lu Tingli nodded again.
Xia Ningxing added, "I'll find a way to get them three a paternity test."
