“What’s with the sigh Yun? Are you alright?” Luhan kindly asked through the communicator. The girl shook her head although she knew he would not even see her action. So she ended up sighed again. “I’m fine Luhan.”

“You don’t sound like it.”

“I’m fine, seriously. Just help me by locating Mr Wu’s study room. I assume his computer would be there.” She said in a high tone but in a slow frequency. The sounds of keyboard being clicked was heard for seconds and halted immediately. “I can’t hack into his system to get the schematic of his house. I think there’s some gap generator installed in his house.” Yunhee cursed under her breath once she remembered the same statement that came from Ms Jung.

She had no idea where to go since the slightly ajar door led her to a surprisingly long hallway. There were series of door that still remained mystery. Anything could be behind those closed door. One thing for sure, her ‘cousin’ might be in one of it.

“I suggest you try finding the gap generator first so I can locate the study room. Once you disarm it, I could help you even better.” Luhan explained but he also tried his luck to trace the position of the device.

Baekhyun shrugged and told her about the possible height of the gap generator. Apparently it might be a four metres high object. It would not make sense if it was installed in the basement. Yunhee nodded with agreement. She heard Luhan said to go with his plan.

“I’ll go to the rooftop while you find Agent 015. A little of teamwork and we shall find out where is he in a nick of time.” The male agent added. There was a little doubtful feeling tugged in her heart but she believed he was not selected to be train by her for nothing.

“I trust you to do it well Byun. Don’t disappoint me okay?” Yunhee carefully said her words before they walked to the opposite directions. It was silent until she heard him calling. “I almost forgot. Go change to your spy suit thing. You don’t want to do your mission in that.” Baekhyun noted and pointed at one of the windows nearby.

Looking at him weirdly she marched towards the pointed window to look through. It was dark but she could see the company’s car parked right outside the huge brick fence. Before she could thank him, he already had gone. Not even his shadow was seen.

“Relax Yun, he’s doing fine. Sehun will help him too.” Luhan suddenly assured. Without t
