A few years ago, your father died in an accident. It happened when you were a teenager, so you had to get up alone. You saw the car plate of the person who hit your father, and you intend to take revenge yourself.

Jeon Jungkook, a rich and well-known businessman in his city. He had just returned from a meeting at a cafe. But when he wanted to reach his car, he felt an injection and fluid flowing into his body, making him faint.

When he woke up, he was shocked because he was in a room with his hands and feet shackled. The room had one bed, one table, and a chair. There, there were also lots of handcuffs and cloth hanging down.

He saw a young girl with her back to him. Like he was preparing something. But when he saw the girl carrying a gun, he just acted calm.

Meanwhile, the girl, she was preparing it and didn't realize that Jungkook was awake. Jungkook, who has his own 'experience', can remove the handcuffs easily.

You turned around holding a gun. But you were surprised when you saw him sitting with his legs crossed. His hands were no longer shackled. He looks at you with a sharp grin.

"Why? You're surprised that I can be free, little girl? You don't know the risks of what you do, hm?"
