Due to an event in his past, our protagonist has become socially awkward.

This boy—Kaito by name—had only one friend: a girl he met online.

He knows absolutely nothing about her identity... she might not even be a girl...

But for Kaito, no matter who she was, she remained a precious friend.

Those around him mocked him, calling him an "otaku," "gloomy and creepy," "unmemorable," etc., and no one even approached him outside of purely administrative matters.

One day, as he continued his isolated existence, his father's remarriage—for better or worse—completely transforms his life.

Kaito suddenly finds himself part of a family with beautiful sisters.

Normally, this might be a cause for joy.

However, he despaired at this—and made a vow in his heart.

"(I'll definitely make this woman cry someday!)"

Gradually, Kaito begins to interact with other beautiful girls, some of the most prominent in his school.

Because of them, the peace of his previous isolated "loner" existence is shattered, and Kaito is thrown into the turmoil of what's called a "fulfilled life."

Will his journey lead him to heaven or hell?
