A/N: Welcome to my brand new fic! Just a heads up this story does have an established Shassie relationship. I originally planned on them getting together during this story, but that would've taken too much longer before getting into the actual story.

I plan on publishing a prequel after this is finished introducing their relationship.

Anyway, I hope you enjoy the new story!

Chapter 1: Secrets Aren't Always the Best

Shawn tapped on his leg anxiously as he stared out the window of the small blue car. The latest case he and Gus were put on was driving him crazy. In fact, it was driving everyone crazy. Buzz McNab, the usually all smiles, outgoing, peppy police officer, no longer smiled or laughed at any of Shawn's jokes. Shawn's best friend, Gus, never backed him up during his jokes, or helped in any attempt to lighten the mood. Juliet, who was usually the more relaxed and untroubled of the group, was very much troubled at this point and rarely left the station, much like her partner. Shawn didn't even want to start thinking about how much of a toll this case has taken on her partner, or otherwise known as Shawn's secret boyfriend of two months. Lassiter has looked at this case from every possible angle more times than he could count on one hand. If someone was to say Lassiter practically lived at the station before this case, they would believe themselves now. The only time Lassiter was caught out of the station was when it was his turn to make a coffee run, or when he was in dire need of a shower and fresh clothes.

Lassiter and Shawn started dating roughly three weeks before the start of the case, and officially called each other boyfriends about a week before the case. Shawn was aggravated that this case was keeping him from seeing Lassiter more often. The few times they would have time together were at the station, where Lassiter wouldn't lift his head from the case file, or at a crime scene, where Lassiter put on his usual facade of hating Shawn. It was clear to Shawn that the root of his anger wasn't coming from the case being so much of a struggle, but more of Lassiter not wanting to tell everyone just yet that they were a couple, and had to pretend that they still had it out for each other. "

Shawn," Gus said directly to Shawn as they pulled into the parking lot of the station. "Shawn," he called again when Shawn didn't turn to face him or acknowledge him in anyway. "Shawn," he said again, louder this time. Gus sighed and reached forward to grab Shawn's shoulder and shake him out of his thoughts. "Shawn, seriously. We're here," he told him as he continued to shake his shoulder.

Shawn turned his heads towards Gus with his eyebrows raised once he recognized he was talking to him. "Hm? Sorry, buddy. Got distracted," Shawn replied simply as he pushed the door open and climbed out of the car deemed the blueberry. He followed Gus up the stairs and pushed his hands in his pockets, still mulling over the case. "It's just the case," he admitted to Gus and watched as his friend sighed and rolled his eyes. "It's a simple case, but it's more difficult than it should be."

Gus turned to look at Shawn and scoffed. "Really, Shawn? You say that about every case."

Shawn shook his head at his friend's opinion. "This time it really is, Gus," he insisted. "There should be a trail to follow, there always is, and I always find it," he paused to think about how this case would hit a dead end after every single lead. "It's as if the Cinco Reyes know when we're onto them. And that's impossible," Shawn mumbled mostly to himself as he stepped into the police station behind Gus.

Gus stopped in his tracks when Shawn was no longer by his side, but staring at the floor in thought. He backtracked the few steps to Shawn and nudged him in his side with his elbow. "Shawn, can you just hurry up and say hi to Lassiter so we can get lunch?" He whispered into his friend's ear as he glanced at Detective Lassiter's desk. "I still don't know why you insist on swinging by everyday. He never acknowledges you," he pointed out to his friend before he got the chance to step away.

Shawn turned to face Gus as he continued to walk backwards towards Lassiter's desk. "Today I'm putting my foot down. You should be proud," he declared with a half smile to the only other person who was aware of the relationship.

The walk from where Gus was standing to where Lassiter's desk was located was fairly short, meaning Shawn only had a few moments to prepare himself for what he was going to say to the man he was confronting. When he reached the desk he leaned forward and placed his hands on the edge as he bent down slightly. "Hey, Lassieface," he beamed with a smile to the man sitting in front of him. Although Shawn was trying to start a conversation, Lassiter was not having it. Just like usual, he thought to himself before he cleared his thought in an attempt to make his presence known.

Lassiter simply sighed at the disturbance and put his pen down for a moment. "Spencer, will you please go away? I'm trying to do actual police work here," Lassiter hissed at Shawn without bothering to look up at him.

A switch flipped inside of Shawn and he couldn't take it anymore. He was tired of Lassie ignoring him and he was tired of all the hatred, even if it was just to fool the rest of the department. He bent down closer to Lassie's head before he spoke. "Can I speak with you in private for a moment, Detective?" Shawn demanded.

The change in emotion in Shawn's voice was so drastic and so sudden, Lassiter couldn't help but look up to see if he was being serious or not. Lassiter fought hard to hide the shock from his face at the sight of how angry Shawn looked. He nodded his head slowly before he pushed himself out of his desk chair and turned to walk in the direction of the investigation rooms.

Lassiter checked his surroundings carefully before he pushed the door open to the empty room and stepped inside. He waited for Shawn to follow him in before he shut the door behind him and took another look through the small window, making sure no one saw them.

Shawn rolled his eyes at his boyfriend's paranoid behaviour and sighed as he leaned back to sit against the metal table. "You know, you really should stop being so paranoid," he commented on Lassiter's behaviour.

Lassiter rolled his own eyes at the statement as he leaned against the brick wall, opposite of Shawn. "Well, I'm sorry if I'm not quite ready to let the entire police department in on our personal relationship," he informed Shawn for what felt like the 1000th time.

"I understand not telling everybody," Shawn said in agreement with Lassiter. "But I don't understand why you won't tell Jules. She's your partner. Hell, she's your friend," Shawn pointed out, while fighting to keep his voice at a controlled volume.

"If you want me to tell O'Hara, fine. I will," he reasoned with Shawn. "But I know that's not what you really want to talk about," he objected with Shawn's focus in the argument.

Shawn glanced down to the floor and crossed his arms as he pondered how to say what he needed to. "I miss you," he blurted out without much thought to the words. As he glanced back up he could see the confusion in Lassie's face and he elaborated on what he meant. "It's been two weeks since you've been to my apartment, or since I've been to your's, and I miss spending time with you," he clarified. "Yes, I understand you're just doing your job and working on the case, which technically I'm supposed to be working on too, but I just can't help but feel like you're using the case to your advantage to ignore me, or avoid me for some reason."

Lassiter's heart broke upon hearing those words fly out of Shawn's mouth. It wasn't until that exact moment that he could see just how beat down and hurt Shawn was. He immediately stepped forward and placed his hands on the shorter man's shoulders. "Shawn, I am so so sorry you feel like I've been avoiding you," he apologised to Shawn before explaining himself. "I never meant to ignore you, I've just been trying to solve this case as quickly as possible so we could have more time to ourselves."

Shawn nodded his head at Lassiter's explanation, although he still felt a twinge of anger at the back of his mind, and he needed to get it out. "I just don't understand why you can't leave the station once in awhile to see me. It doesn't even have to be anything special. Just spending the night at my place, so that way I know you're not pushing yourself too hard," Shawn mumbled just loud enough for Lassiter to hear. He started to say something to Shawn, but he got cut off. "Even Jules leaves the station to get a few hours of sleep in her own bed," he said harshly.

Lassiter waited a moment to reply to Shawn, making sure he wasn't going to get cut off again. "How about this. I will spend the night at your place tonight. I'll leave the station at 10:00, and be there no later than 10:20. We can do whatever you want," he suggested as he watched Shawn's face light up in front of him.

Shawn could feel as the grin spread across his face at the idea of Lassie finally spending the night with him after who know's how long. He also felt as the grin turned into a smirk at his latest idea. "Sound's like a plan. Except for one thing," he started to say and waited for Lassiter to raise an eyebrow in confusion. "Make it 9:00 instead of 10:00."

Lassiter smiled as he rolled his eyes. It didn't surprise him that he was trying to manage as much time with him as possible. "Fine, 9:00 it is."

Shawn immediately leaned up and closed the gap between the two of them, and gave Lassiter a quick but sweet kiss before he started for the door. "Oh, and one more thing. Don't forget to tell Jules where you're going." He couldn't help but smirk as he watched Lassiter's jaw drop wide open, before he turned and walked out of the interrogation room.

The smile that had taken over his face didn't falter even the slightest on his way back to where Gus was waiting for him. As Shawn rounded the corner, Gus couldn't help but raise an eyebrow at the sudden gleefulness his friend had. "What exactly did you say to him?" Gus asked, in shock.

"Let's just say Lassie's coming over tonight," Shawn said cheerfully. "Now, where were we? Jerk Chicken?" Shawn asked his friend the no brainer question with the smile still on his face as he stuck his fist out.

"You know that's right," Gus declared to Shawn as he stuck his fist out to complete the first bump.
