That mark on his neck...
DX was sitting inside the enclosed area while Kai Xin and her best friend, Jane Chu, were sitting at the light blue couch inside the Little Monkey's playroom.
Kai Xin chuckled when she saw DX warning Mo Yuan against kissing the two little girls. The little boy saw DX kissing Kai Xin earlier, and he tried to emulate the older man by chasing the little girls around. He would have done it if DX did not swoop the girls up at the last second.
"You are a boy. You can't just kiss any girls you like, especially my girl!" DX said with a gentler voice than what he usually used with older kids. However, it was obvious that he was annoyed because there was a frown line on his usually perfect expressionless face.
"Kiss kiss..." Mo Yuan giggled.
Mo Yuan was just a few months older than the girls, so it was not like he understood what DX was saying. but it did not stop DX from warning him.
