Xiao YuYi is envying YuYan

It is rare for Xiao FengYin to see Xiao YuYi seemed having fun of him knowing that he won't let his sister get hurt. He was happy at the same time seeing them together. 

Not that the three siblings don't go well with each other, but the two were naughty little ones unlike Xiao YuYi who behaves well and never made any trouble.

Xiao FengYin feel a bit worried though, since his two other siblings are too naughty which might influence Xiao YuYi's good behavior that he carefully taught her.

Encircling her little arms around her big brother's neck, Xiao YuYi excitingly uttered. "Big brother! Big brother! I want to sleep in your room!"

Seeing his behave little sister speaking differently than she used to, Xiao FengYin arched his brow. His fears about Xiao YuYi being silly like his two other siblings made him feel worried.
