Anata, Minaide... ~Chietsu Houshizuma Miyuki~

Life was all going so smoothly. The protagonist had a big client on the hook and was about to close the deal. But before it was done, the contract got torn up. Suddenly he was laid off, and he even lost his girlfriend Miyuki.

Six months later...

The protagonist met another laid-off coworker from his company. Apparently after firing everyone a certain senior coworker closed the protagonist's deal, and was now happily married... to Miyuki. It was just a rumor, but the protagonist's guts boiled with outrage.

A jagged seed was planted in him that day, and as it grew he developed a revenge plan that took no heed of the future or his livelihood. He would destroy the man who had taken his life. Along with a small army of downsized coworkers, he stormed the company, and while her new husband watched, he ravished the bride that once loved him.

The night is long, and there's much to do.
