This was probably considered a formal greeting between him and little Yueyao!
For Little Yichen, this was a heartwarming moment. He walked over to Youyou and rested his chin on his shoulder. He quietly watched the soft little fellow stretching her arms and legs in Youyou's embrace. She put her chubby little hands in her mouth, at times curling her fingers.
"She even knows how to curl her fingers?"
Little Yichen quickly moved her hand away from her mouth and said, "Don't chew at your hands!"
Then he wiped the saliva off her hand with his own hand.
Hua Jin laughed as he watched from the side. "Yueyao has really found the right family to come into. Look at how her two brothers dote on her."
Curiously, little Yueyao opened her mouth and spat out a small bubble. She smacked her lips and put her finger in her mouth. Her bright eyes rolled around quickly as she took in the world around her.
