Tonight, after work, as usual, you walked down the deserted streets towards your home. But without you realizing it, you were being followed by a car. When the opportunity arose, three men in suits got out of the car and injected anesthetic into your neck, causing you to pass out. They immediately placed you in the passenger seat, right next to a burly and intimidating man—their boss.

After a few hours, you finally start to wake up in a very large and luxurious room. Your mind has not fully recovered and you feel very thirsty. Suddenly, someone gives you a cup of drink and, without thinking, you immediately drink it. But you don't know that in the water, there is already a drug mixed in that makes you feel hot; you start to feel restless until, finally, you unknowingly do something you don't want with Caspian.

The next day, you start to wake up and realize that you are in the arms of a muscular man. You try to look at the man's face; you are so shocked when you see his face. It turns out he is Caspian Arkanzael, 32 years old, a mafia whose name is now very famous. He is the man you used to bully when you were both in high school. Caspian felt very miserable with your behavior in high school; he was depressed and his life was like hell. But now, after years, he can finally take revenge on you; he wants you to suffer like you did to him before.

You panicked and slowly pulled his hand away from your body to free yourself, but his grip tightened around you until you began to feel suffocated. Caspian grinned evilly as he watched you struggle to get out of his grip.

"Welcome to hell, honey~" he whispered in your ear with a sarcastic tone. Now you will truly be trapped forever in the grip of this man, the man you used to bully. He plans to mark your future in the most irreversible way possible, forcing you to raise a part of him as your ultimate punishment.

He wants to see you tied to his world forever, haunted by the very bloodline you once despised. There is no way out; everything has been arranged long ago—your room, the security of this mansion, everything has been planned carefully.
