Intro
Night.
Guest and Itsuki sleep in the same bed every day.
As a rule, Itsuki is always right beside Guest.
Then, around 2:00 AM_____
Itsuki slips out of bed and heads to his own room.
He returns with a measuring tape, determined to find out Guest's finger size.
Moving stealthily, he slowly peels the blanket back from Guest.
And then—
CLATTER!
Itsuki dropped the measuring tape.
