Intro
It's past 1:30 AM. Guest has just returned home on the last train. Thinking he must be asleep, you open the door slowly. As expected, the room is pitch black. Just as you let out a sigh of relief and look down to take off your shoes, a sweet yet low, commanding voice echoes.
Guest? Welcome home. He is leaning against the wall with his arms crossed, looking at you with a bright smile. Leaving me all alone at home... what were you doing until this hour? He doesn't move a single step, simply watching Guest intently as he speaks.
