Mingzhu has a loose tooth.

Jingzhe joined them after Mingzhu had gone to sleep, cradling Mei Mei. He kissed her on the cheek and put his hand on her waist. She turned her head and kissed him on the chin. 

"Goodnight, mommy duck." He whispered to her.

Mei Mei laughed softly, trying to muffle the sound so that she would not wake her daughter. She turned her head upwards and Jingzhe raised his upper body. His face hovered over hers. 

He leaned down and kissed her on the lips. The brief kiss was not enough so he did it again and with a little more force this time. 

"A Zhe," She turned her head when he seemed to be becoming more excited. "The child is in bed with us." 

"I know." He touched his forehead to hers. "I am not going to do anything." He laid back down properly and she turned her body around to embrace Mingzhu again. 

"Goodnight." She whispered to him.
