The violence in South Seoul has increased by 20% and the police are nowhere near catching the gang. The gang with 7 members, only known as Infinite. The police don't even know the members' names.

Chief Yunho is tired of being two steps behind them.

"Hey, Junsu. Call Hye Mi in here. Maybe she can help us." Yunho said.

"Yes, sir." Sergeant Junsu went to the break room where he found Hye Mi dazing out the window.

"Hye Mi, Chief wants you." Junsu told her.

"Hmm?? Arasseo." Hye Mi shook her head and stood up to walk to his office.

"You wanted to see me, Chief?" Hye Mi knocked and said.

"Oh, Hye Mi. Yes come in." Yunho gestured for her to sit and she did. "As you know, South Seoul has an increased violence rate of 20%.." Yunho started.

"Yes, and it's believed the gang Infinite is the cause of it. However we have nothing that ties them to it, nor do we have any information on any of the 7 members." Hye Mi replied.

"You've read the report I see. Well, that's where I think you can help us. No one has seen you since the incident. And well you're a female." Yunho stated the obvious, it made Hye Mi cringe. "So, I want you to go to South Seoul, infiltrate Infinite, report back information and get out. No problems, no paperwork, and definitely no falling in love. Do whatever it takes. Go to school with them, if they even do that. Report back every two weeks, that way they won't get suspicious. Understood?" Yunho said.

"Understood. When do I start?"

"Now, if you can. Here's their picture off a security camera. Go see Yoochun for any background you need or school records." Yunho shooed Hye Mi out the door.

Yunho turned and stared at a picture on his desk. "I will avenge you, my love." he said.
