"I promised Mommy not to tell anyone." Xiaoyu shook his head.
His mother had told him not to tell anyone, which included his 'Daddy' as well.
That meant, Xiaoyu could not reveal her identity to this beautiful grandmother before him either.
"Am I just a stranger to you?" Song Changwen prompted further as she tried to fish for more information.
However, Xiaoyu simply shook her head. "Mommy said that I must behave like a trustworthy person. Since I promised Mommy, I can't tell you."
As he spoke, he dropped his backpack on the ground and covered his mouth with both hands.
That would prevent him from accidentally letting the words slip out.
For a kid his age, Song Changwen was surprised that he took being trustworthy so seriously. She suddenly lost the will to persuade him further. With a smile, she patted Xiaoyu on his head. "That's right, we must all keep to our promises. In that case, I will stop asking you that."
