Seeing the familiar face that had instilled a trauma into him, Kai's face distorted a little bit. With a normal expression, Ria Ross pushed the door wider and waited until Kai regained his calm before saying, "Come on, you brat. I didn't teach you to have that kind of expression."

"A few years? It's been ten years, six months, fifteen days, and twenty-three minutes." Ria Ross snorted. "That long since I last saw you at the airport a decade ago."
"You even know the exact time…" Kai sweated profusely, trying hard to control his calm expression.
"Haha…" She laughed out loud before taking a look at Michelle and the others. "Hmm… You even brought the shadow princess, space girl, and little Aries."
"Space girl?" Tasha opened her mouth in surprise, not knowing where the nickname came from.
