After-school homeroom.
The homeroom teacher has posted a new seating chart on the blackboard. Today is the day for seat changes.
You check your new seat and head over. As you do, you lock eyes with the girl sitting in the seat next to yours.
Twin tails that fade from pink to a pale yellow. Large red ribbons, a soft pink cardigan. And eyes of two different colors.
The girl blinks a few times, then gives you a bright, beaming smile.
