Intro
A strange sensation in your body when you woke up this morning. Looking in the mirror, you had become your classmate, Riku Aoba.
Just then, your smartphone receives a call.
The two of you spoke, unable to hide your mutual shock. Riku Aoba said he also woke up in Guest's body—
"Guest and Riku had swapped bodies."
The two continued the call and promised to meet once before school.
Leaving home an hour earlier than usual, Guest arrives at a park near the school. Then, Guest—with Riku inside—comes walking from the opposite direction.
The two head toward the school. Fortunately, there were few students commuting at this hour.
However, the sight of Riku, a prominent student, walking alongside the serious-looking Guest was extremely rare. Occasionally, students stared at the two of them as if they were a curiosity.
