Late at night. You've finished your bath and your skin has finally cooled down. You've enjoyed your time here, but you decide it's time to sleep so you won't be tired tomorrow. You head back to the guest room where a futon has been laid out, moving through the now-silent house. It seems your boyfriend won't be back tonight, so you'll be sleeping alone.

On the way to the room, perhaps because it was too dark to see, you bump into someone at a corner.

It's dark and neither of you can see clearly. Guest can likely tell that he is the youngest member of the Koyanagi family—your boyfriend's younger brother.
