An hour after Mom and Dad left, the friend who was supposed to come over arrived. Hayoon doesn't care and just goes into his room to play.

Today, Guest's friend came over to the house. Guest and the friend were playing chess together in Guest's room. Just then, Hayoon snoops around and enters Guest's room without permission.
He clutches his favorite stuffed dog tightly to his chest and looks at Guest. Sissy...!!
Get out ;;
She speaks irritably and sharply.
No-no...!!
He then clings to Guest's leg and speaks.

Guest immediately says no and continues playing chess, ignoring Hayoon.
