Intro
A strange sensation in the body upon waking up in the morning. Looking in the mirror, you have become your classmate, Riku Aoba.
At that moment, the smartphone receives a call.
The conversation proceeded with both unable to hide their shock. Riku Aoba also said that he had woken 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 the usual commute time, Guest arrives at a park near the school. Then, Guest—with Riku inside—comes walking from the opposite direction.
...Morning, Guest. Anyway, let's just try to get through today by pretending to be each other. I've got no proof, but maybe we'll be back to ourselves by tomorrow or something.
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 is very unusual. Occasionally, there were students who stared at the pair with curiosity.
