No ones pov

Kyuhyun laid there in his king sized bed, his back on the soft bedding and his arms up in the air holding his mini iPad. It was getting late, his body was exhausted but his mind didn't allow him to fall asleep. Worst of all, there was school tomorrow. He sighed with the mini iPad in hand, rolling to his side. 

"I don't like this..." He muttered, hugging the device close to his chest as he shrivelled up into a ball. His mind gave in, he knew he was smart and his intelligence was not to be rivalled but this case had become nothing but a labyrinth to him. The walls left like it was closing in and locking up every path that allowed his to reach the answer. He couldn't help but walk round and round in circles until some part of his body would soon eventually explode. His sighs didn't stop and neither did his curiosity towards his late teacher. 

"Go to bed Kyuhyun, it's getting late." A voice came out. Kyuhyun sat up on his bed and pouted at the well lit screen to his laptop. In front of his bed was his desk and where his laptop laid. The screen showed Sunggyu fiddling around with some papers. He had his head down and a cup of what Kyuhyun could only presume was smelly coffee on his desk. The younger decided it was best to Skype the older policeman as he was one of the ones in charge of the case. Unfortunately, the disappearance of the killer was so sudden and the death of the teacher had managed to cause a huge dent in the case. The police force had no useful information and now with their culprit dead, so was their lead on the case. 
Sunggyu sighed and pinched the bridge of his nose. It was currently 1am. He had dropped Changmin and Kyuhyun off around 6:30pm and gone back home straight after only to do work. He didn't have any breaks as he would rather work until his body was to break down. There was always a possibility that as soon as he looked away, vital information could have been lost. 
Kyuhyun looked at the older with eyes full of worry.

"I can't... If there's anyone who should be going to bed, it's you. Has Woohyun hyung not arrived back home yet?" Sunggyu flinched at the name. Woohyun was Sunggyu's boyfriend. Like Sunggyu, he quite liked the idea of the Y.C.K trio. From time to time, he would sneak information to them if they needed it but it wasn't easy for him. Why? Well, that was because he was in the higher ups. There were the normal policemen, then the detectives such as Sunggyu, the chief of police and the ones who looks down at the chief of police, the commanding voice. That was what Woohyun was. The chief might be the chief of police in just that station for Seoul but Woohyun was in charge of all the stations that were situated within Seoul to a 100 mile radius from it. Sunggyu at the time had heard of Woohyun but never knew how he looked. 
They met one fateful day when Woohyun was due to make around at their station to check up. Unfortunately someone decided to barge into the place at that day and hold him at gun point. Everyone froze as the man began shouting threats of killing Woohyun if the police didn't free his son from jail after being put in for attempted murder. Thinking quickly, armed with the intentions of only saving an innocent human and nothing more, Sunggyu walked forward and pushed the man's hand which was holding the gun, upwards. He then grabbed onto the man's wrist pulling it behind and swiftly slides behind the man, whilst holding on the man's back with the free one. The man groaned in pain from the position he was in. Woohyun couldn't help but notice Sunggyu at that point. He soon fell for Sunggyu's charms and did his best to woo the man but Sunggyu would reject him each time. His excuse being that it wouldn't be right but Kyuhyun, who was there at the time, knew Sunggyu's true feelings and talked him into accepting Woohyun. It had only been 2 years since Sunggyu said yes and now they live together in their 3 bedroom house with 2 driveways and a back garden. There were times when Woohyun would have to work well into the night but he never failed to come home and snuggle in with Sunggyu. However, with all this happening, Woohyun had no choice but to work overnight for a couple of days with the only satisfaction of knowing that Sunggyu would be there at home waiting for him. 

"No... It's been 3 days and with what happened today in the interrogation building, in afraid it's going to be awhile till he's able to come home." Kyuhyun gave a small smile.

"Don't worry! Before we know it, the case will be cracked and Woohyun hyung will come back home to you every night." Sunggyu gave a tired chuckle. Even his voice sounded drained. 
"Hyung, go to sleep now. I will too. I'll talk to you tomorrow ok?" A defeated sigh came from the older when he nodded and walked over to his bed. Kyuhyun made sure to wait until he heard the change in Sunggyu's breathing to signify he was asleep before going to bed himself. 
Being an only child, Kyuhyun found himself often feeling lonely. From little, he and Sunggyu would keep their skype on throughout the night until they were both asleep and none of them would leave. It made Kyuhyun less lonely and scared of the night as someone was there with him, even if it was just a computer screen. That he forgot to mention, they both of them were childhood friends who was at first, forced to become friends as Kyuhyun didn't have any. 

------------------------------------------

He woke up feeling exhausted but he managed to get some form of sleep. The hours he got managed to satisfy his brain but not his body. A lazy day after school was needed but he knew that any longer he took in trying to crack the case, it would mean more sleepless nights for not only him but Sunggyu aswell. 
He sighed, clutching onto his side bag handle. Oh how he really didn't want to be in school. He took out his mini iPad and began to press it's buttons, looking for any clues and even altering some of his notes to make them readable and to fit his memory. He wished now he had taken a video of it all. All of his notes and findings would have to be given in at the end of the day to Yunho for inspection and filing. 

"Video?!" Kyuhyun mumbled, looking up from his iPad mini he found himself finally getting somewhere. A smile came to his face as he stuffed the iPad mini into his bag and skipped his way to class. 

Kyuhyun could see Changmin already inside the classroom, sitting where he usually was. The two of them didn't have the same form but was together for most of their lessons. In fact, the one where both of them would be together and sitting next to each other was first on the agenda for today. A faint blush came to Kyuhyun's cheeks when he remembered the small kiss Changmin planted on his check just yesterday. He shook his head and continued to walk to his class, hoping that Changmin wouldn't see him before first period. 
He sat down on his desk, being the first on there he was quite happy. The clock read 8:21am. He sat back on his seat and took in a deep breath. He laid his bag down on the desk in front before he took out his mini iPad once again. 
He clicked on the internet and searched for the Seoul police website. It was a website for people who might need help or any information about them. Based for foreigners since they might have just moved into the country and won't now their way around. However, behind that smile and helpfulness, the website was only a front for something more, way more. It was a database program for the force in order to store useful information such as blueprints to all the station buildings and government owned buildings. It had access to the CCTV cameras from the city of Seoul to as far out as Busan. It was all that jus to a little password and username, not to mention the 20 firewalls and codings which needs to be breached for hacking to take place. That is not with the right login. The police force had compulsory knowledge which meant all the information that was important and needed, they were able to access it. Detective had something more personal, being able to get accounts of the person and first hand accounts of everything. The chief and commanding voice had the same thing, only difference being commanding voice had a wider range of people on their list they could monitor. 
Kyuhyun logged in as Woohyun. Hacking wasn't needed at the older practically gave him his login when they first met, hearing of what Y.C.K was, he immediately liked them. He wanted them to had as much access to information as the police did or even more. He didn't care if it was breaching government and international information but he did care about the lives they were saving. Kyuhyun did things such as hacking but why do something illegal when you could do it the legal way. The screen greeted him was Commanding Chief Nam Woohyun before asking him where he would like to go. Kyuhyun clicked onto the blueprint storage file which had blueprints of every government building and high profile facilities. He clicked onto the interrogation building blueprint. The screen turned black before neon blue lights flashed cross the screen and began moving into place of the room. It showed and outline of the inside of the building and it's different floors. In a split second, he found where him and Changmin were sitting just yesterday. They were located on the South whilst the table and chairs where the culprit sat was facing east. The killer of Miss Kim sat in the north just opposite him and Changmin. He closed the file and moved on to the CCTV commanding room. He hoped that there were cameras at the right place. 
The screen split into 16 segments, each showing a part of the building. A clock at the corner showed Kyuhyun he was viewing the building live. His eyes quickly scanned for the designated areas. 

"Camera...1...8...and 12." He muttered as he found the camera's that showed him what he wanted. Camera 1 was right on from of the culprits desk to see their reactions when it comes to the questioning. 
He was about to look for the CCTV videos of yesterday since the police never throw away their interrogation videos of clue findings when Kyuhyun started to hear footsteps and quiet chatting along the hallway. 

'Approximatley 3 meters away.' In a flash, he stuffed his mini iPad in his bag, before writing his findings on the notes page in case he forgot them. He put his bag under his desk and sat up with his hands on his laps and a sweet smile sprawled across his face. 

"Good morning Kyuhyun!" He heard a loud bang of the door being opened. Immediately, he knew who it was, even without the voice that alerted him. The other had a big smile on his face. Showing his top gums.

"Good morning Eunhyuk ssi." Eunhyuk walked closer to Kyuhyun, his face change from a smile to a pout. 

"Still with the formalities? We've been friends for a year already!" Many people get angry at Kyuhyun for this. The only one he didn't use formalities with was Yunho,  Changmin, Woohyun and Sunggyu. Other than that, he would. Kyuhyun gave his best smile. Usually a smile would make people forget and forgive Kyuhyun for this silt habit of his. It wasn't that he didn't want to called them friends, it was that he couldn't. He didn't let him get too attached with someone, at least not that many. 
The bell rang, signalling the start of class and the start of form. All they had was 20 minutes if registration and catching up on things. Sometimes, their tutor would maybe tell them stories or teach them their specialised subjects. With form ended, Kyuhyun gathered his things and went to his first lesson. 
With each step he took, it seemed to increase his breathing and heart rate. It was science and that meant Yunho and Changmin would be in the same classroom as him. He sighed, feeling his cheeks start to grow hot and redden from suddenly remembering back to when Changmin kissed him on the cheek. His feet dragged him all the way to the classroom, from the window, he could see Changmin was already there waiting for him. He hesitated for a bit but opened the door, walking to his designated seat.
