Nono from Another World

By common sense, once you transmigrate, you become the protagonist, become invincible, and reach the peak of life.

But what if you transmigrate into a girl?

A man who had been a shut-in for more than twenty years suddenly discovers that all his common sense seems useless...

But as a transmigrator, even if he becomes a girl, he must defend the dignity of a protagonist to the end!

Even if all common sense no longer works, at the very least... love is still possible!
