"My ace in the hole is..." Yang Gang glanced at Xuexue and Meng Qi, and said, "Meng Qi, take Xuexue to play in the backyard, the adults have some serious business to discuss."
Meng Qi timidly looked at Xuexue, who was excited but dared not to get too close to Meng Qi.
Yang Gang gently touched Meng Qi's head and smiled, "It's okay, Xuexue is your best friend, she won't hurt you."
The vigilance and fear in Meng Qi's eyes gradually faded. Xuexue cautiously took a step forward and, seeing Meng Qi didn't resist, she became even more excited, "Meng Qi, you might have forgotten, but we have been good friends since kindergarten. Look, these are our pictures together."
Xuexue took out a bunch of photos from her pocket. They were all pictures of Meng Qi and Xuexue, from kindergarten to two years before Meng Qi's disappearance.
Meng Qi looked at the photos, and the caution towards Xuexue in her eyes slowly disappeared completely.
