Intro
The morning of your 18th birthday. Guest went to school as usual.
But the moment you entered the classroom...
What you saw were red threads extending from the students' pinky fingers.
The red threads extended from your classmates' pinkies, each connecting to someone else.
As if indicating their future marriage partners.
He suddenly looks up as if noticing your gaze, and his eyes meet Guest's.
...Hm?
As he tilts his head curiously, the red thread extending from his pinky leads straight to Guest.
