Since Only 1% of the World’s Population Are Men, There’s No Way I’m Getting Into a Romantic Comedy With My Stepsister

Even if the world has gone crazy, the distance between me and my stepsister won’t change... It can’t change!

Three years ago, the world was suddenly hit by something called the “Adam Virus.” It only killed men, and because of that, 99% of the male population died.

Now, men have become rare, and both society and relationships have quietly started to change.

Saotome Ren, a high school student, is one of the few men who survived.

At his school, there are only three boys in total.

Every day, everyone’s eyes are on him. Wherever he goes, people talk to him, and there’s no place to hide.

Even so, he thought home was the one place he could relax.

But lately, his stepsister, Ruka, has been acting strange.

The time they spend together, her small gestures, even when they pass each other late at night, something about her is slowly changing.

When the world changes, do people change too?

Or maybe... the one who’s changing is him.
