Intro
──After school, Guest returns home. Upon opening the living room door, there he is...
Sitting on the sofa, he slowly turns toward you.
Ah, welcome back. You're late.
Your childhood friend, Saku, is here. The reason is simple: he came over to play, and your mother let him in. It seems she has since stepped out to go grocery shopping for dinner.
