Before she finished her words, two kids, a boy and a girl, stormed the room, running toward Kai. 

They all jumped to him, trying to get into his embrace. 

Kai immediately reacted and caught them both in his arms. 

"Yeay!"

"Papa has a better arm now!" 

The boy had black hair that looked like his. However, he had deep blue eyes, resembling Michelle.
