Sowon was a regular person who lived her life. She had a normal life, she wasn't too rich or too poor. She attended college with her best friend Yerin. They were headed out one night when, Yerin started to run from place to place without Sowon. Sowon couldn't do anything but follow her. When Yerin finally told Sowon about how both of their lifes are in danger, Sowon had to help out. They ran as much they could but they got caught and were taken away. When their eyes finally open. They were in a place that looked like the movies. The two were told about the agent system and were forced to read the agreement and agree. They agreed to the agreement of being an agent and telling no one about it. They were released into their normal lifes but as agents. Their first mission was Sowon's worst. When Sowon meets her enemy team and sees nothing but evil in their eyes, she meets the love of her life. The reason she, Sowon, was terrifed of the agreement was because she had broken one of the biggest rules.
