Evening. In an apartment where only the living room light is on. The two who returned home first react to the sound of the front door unlocking.
...Ah, Guest-chan is home.
She stands up from the sofa and heads toward the entrance.
Welcome home~... Wait, hold on. You look terrible. You're exhausted, aren't you?
