They used the stairs to the highest level of the hospital. Changmin glanced at mini computer in his hands and frowned deeply. The signal was obviously at the level they currently in, but there is no a single door, or window, or even a hole. They looked around, hands touching everywhere on the walls to examine if there is any possibilities to enter the level. None.

"Are you sure it is the right signal?" Yunho asked Changmin, a bit angry. Changmin nodded which only received sigh from them.

"I think we have no other choice except one," they looked at Taecyeon.

"What? How?" Junho's eyes widen as he moved closer toward the tall man. Ok Taecyeon, one of the genius idol that he have ever met. He might looked and acted childish most of the time, but when it is about thinking, he is the best to rely on.

"From inside the hospital,"

"But...impossible..how are we gonna be able to come up to this high level from inside?"

"Be their staffs,"

(Inside the hospital)

Junsu, Junho, Wooyoung acted like regular visitors, while Jaejoong, JunK and Yoochun became one of the hospital's patients. The tallest, Changmin, Yunho, Taecyeon and Chansung became the hospital's doctors. Taecyeon managed to 'borrow' the hospital's uniform from the laundry room with the help of a middle-aged woman.

"We need to split, but move in the group. Understand?" Yunho ordered them via the spy ear. Each of them responded except for Jaejoong. He was somehow are immersed in his own thought. He looked around the place and tried to remember something. A piece of his memory seemed to fall somewhere, like deja vu.

"Jaejoong, do you hear me? Don't act on your own," 

"Roger," he answered half-heartedly as he rolled his eyes. He hates it when Yunho acted like that towards him. Though Yunho is right, but he still dislikes it. He then looked at JunK and Yoochun who are not far from him.

"You shouldn't get involved into this at all...haishh~" he thought. A sudden beep was heard and Chansung's voice was heard.

"Nichkhun hyung will be alright, right?" his voice sounded afraid which flickered Jaejoong's guilt even more. He studied JunK's expression. He only knew about JunK from GD and Top in which they are also friends. JunK was acting exactly like him. Hid his anxious and fear behind that calm and expressionless. 

"He will, Chansung-ah...we will save him no matter what," Junho's voice lingered inside his mind. No matter what? No matter what...

"I will help you no matter what," he heard his own voice inside his mind. That when the pieces connected together. He closed his eyes deeply to remember it back clearly. Unknown to him, Wooyoung is staring at him from his spot. He made sure himself not to stay far from him. Jaejoong instantly looked more serious as he looked around the place. He took his steps away from the place silently, making sure that none would realize his action.

"I remember...Khunnie, wait for me..."

(Chief's office)

Nichkhun stared at nothing in front of him. He felt numb and empty. Exhaustion clearly took over his slim body. His face looked pale as if the blood been drained out. The group managed to save him before it gets more dangerous to their 'subject'. The Chief is now looking at him from his seat. The slim Thai Prince are sitting on the floor, leant against the wall with his stare at nothing in front of him.

"Chief, he is too weak right now. The dose are taking longer to dispose this time. I think it is because we put too much earlier," one of his men told him. The Chief sighed deeply, still staring at him.

"But,
