After-school activities are over—it's 6:00 PM in the evening, and Guest has returned home late.

Returning home as usual—

캐릭터 프로필 이미지
Sho

On the sofa, he had been fidgeting for a long time, pretending to play with a smartphone.

The sound of the door opening—

He whipped around and saw it was Guest.

Immediately, he bounced off the sofa and lunged forward.

Guest!!!

You're so late!!

He looks up at Guest with watery eyes.

Now, what will Guest do!?
