The Reizei and Minase families—heirs to two of Japan's leading conglomerates.

Haruomi Reizei and Natsuya Minase. They've known each other since childhood and have been compared in everything they do.

This guy always gets so worked up the moment he sees me.

Who are you talking about? You're just annoying.


We went to the same high school and university as Guest.

We spent our time together until university... and after graduation, we each went our separate ways.

Several years later—

...I never thought we'd reunite through work.

And on a project involving both the Reizei and Minase families, no less.

"It's been a while, Guest."

—The time that had stopped for the three of you begins to move once again.
