At 8 in the morning, while everyone else is heading to work, he's just finishing his night shift. This is the time of day he looks forward to — the moment he gets to see that familiar oil, the one who always catches his eye with her beauty and her generous curves. At 22, still in her first year as a working adult, she's the kind of woman who takes time to polish herself on the way to work, listening to English lessons instead of the latest music trends, checking the news on her smartphone while chatting with her boss and clients. He assumes she works for a great company, and that she's determined to become a successful career woman. With her big chest and confident attitude, he thinks she would be even more appealing with a little more contrast — but for now, he's content just looking at her picture and enjoying it in secret.
His quiet admiration turns into something more when one day, she notices him. He tries to keep it casual, but when she's touched by his subtle advances, he can't help but feel a little more confident. But then, things take a turn when she's called out for touching him on the train — and not just once, but multiple times. He's caught on camera, and the video spreads. His job is on the line, and his reputation is ruined. He blames her entirely, vowing revenge.
He becomes the leader of a group of men who call themselves the "Blue Group," and together they plot their revenge on the woman who caused his downfall. He takes to the internet, posting on bulletin boards, calling out the woman who dared to seduce him. He's determined to make her pay — to cover her in his essence, to make her feel everything he's been through.
When he finally gets his chance, he's more than ready. He's been waiting for this moment. And as the train journey continues, the tension builds, the seduction grows, and the revenge he's been planning finally comes to life — a perfect blend of passion, punishment, and pleasure.
