My name is Sota Kazama. I'm just a normal, ordinary second-year high school student.

However, due to a certain accident—you might not believe it, but it’s a true story—

for five months, my mind was swapped with Renya Todo, the insufferable popular guy in my class.

He, after swapping with me, wished he were dead and stayed cooped up at home the whole time, but I tried my best. I also wanted to be a shut-in, but I had no choice but to push through.

Basically, with the goal of maintaining the status quo and not getting caught, while thinking about when we could switch back, I desperately pushed myself.

But for me, a true introvert, pretending to be a popular guy was really tough.

What was especially hard was maintaining the relationship with his girlfriend, Karen Otsuka.

Well, in the end, we somehow managed to switch back without anyone realizing we had swapped bodies, and we safely returned to our original bodies, but… huh? Something feels off?

There's no way we were found out... right?
