Xu Jinzhi choked up for a moment, feeling that Tuantuan's answer seemed alright, but it slightly deviated from the response she was looking for.
So, Xu Jinzhi briefly fell silent for a few seconds before trying a different approach, "What Mom wants to ask Tuantuan is, which little sister are you talking about?"
Was it Xie Xingyao? A new little friend? Or was it what she thought it was?
However, Tuantuan stayed silent, blinking at Xu Jinzhi with a face of innocence, as if he couldn't understand what his mom was saying at all.
After a staring match that lasted more than ten seconds, just when Xu Jinzhi thought Tuantuan wouldn't answer her, Tuantuan, with his childish voice, earnestly told Xu Jinzhi, "It's my own little sister."
Tuantuan remembered what Yihang had said before, Yaoyao wasn't from their family, so they did not live together nor call his parents mom and dad.
