Once in a Lifetime

Part 9

"Y/N?"
"C-Chief inspector?" I stuttered as I opened my eyes and saw my boss waking me up.
"Why are you still here? I told you not to overwork yourself!"
"Sorry chief, I got carried away with solving the ongoing murder case that I haven't even realised it's gotten so late."
"Yeah I can see that. Good thing you have a boyfriend who cares for you."
"W-What?"
"He called the office some minutes ago asking for you because you weren't answering his texts nor calls. Didn't even know you have a boyfriend so I'll take this opportunity to congratulate you!" he smiled and shook my hand.
"T-Thanks chief."
"Off you go now. He's probably already waiting for you outside."
"HE WHAT?"
"He told me to tell you that he'll pick you up."
"Oh, uhm, thanks again chief. See you tomorrow!" I said as I hastily took my stuff and left the office.
"H-Hi." I said entering Taehyung's car.
"You are supposed to be home at this hour Y/N."
"I know it's just that I-" my sentence got cut off by Taehyung's lips crashing on mine.
"No excuses." he said breaking the kiss.
"Why are you here anyways? Sorry if I got you worried by not answering your texts and calls but I fell asleep."
"When your boss told me you're still in the office, I supposed you'd be tired and I didn't want you to drive in a state like that."
"Ohh.."
"Is it really necessary for you to work so much Y/N? I understand someone got murdered but you won't be able to solve the case if you don't take some rest."
"Sorry.."
"It's fine, I just care for you that's all." he said and pecked my lips softly.
"Shall I take you home now?" he asked smiling.
"Yes please." I nodded smiling too.
"When are you gonna come over to my house?"
"Is there enough space for the two of us?" I chuckled.
"More than enough." he chuckled too.
"Okay then, I'll come over when you invite me."
"Can I invite you now?" he smirked.
"No."
"Why not?"
"Because I need to get some sleep tonight."
"Does that mean we won't be sleeping when you come over to my place?" he asked, the devilish grin on his face growing even bigger.
"Sweet dreams baby." I smirked and left.
"I've never seen this type of bullets before. Must be of foreign origin." those were the words constantly replaying in my head as I carefully observed three pieces of cold metal that were in front of me.
"The letters... this is Russian!" I gasped as I jumped from my chair and rushed over to Namjoon.
"The bullets! The bullets are from Russia!"
"Russia? How did you find out?"
"I found the letters on the bullets under the microscope and I realised I've seen it once before... Namjoon I need to go to the archive!"
"But why?"
"I told you I've seen these bullets once before. My brother was shot with them... What if they were both killed by the same person Namjoon?"
"But your brother... that was 12 years ago Y/N."
"But these bullets are almost impossible to find, even on the black market! Listen Namjoon, maybe there's no any connection between my brother's and Sunghoo's murder but the fact that there might be some gives me hope. For 12 years my brother's case file stood on that dusty shelf unsolved and untouched while his murderer lived freely. I cannot let this chance go to waste."
"What do you want me to do?"
"Help me find them Namjoon. Help me lock them up behind bars for the rest of their lives."
"But where should we start from? We only know that the bullets are Russian and have no informations about the manufacturer whatsoever."
"I know someone that could help us with that." I said as I took my phone and dialed a number.
"Who are you calling?"
"Seokjin."
"Seokjin?? As in Kim Seokjin?! But how can he help us with this? He is the owner of an investment company!!"
"That's exactly where lies your answer. During the times of war, his grandfather offered financial support in arming the country's military. That tradition, if you can call it that, continued with his son, aka Seokjin's father and now Seokjin."
"How do you know this?"
"My first mission. You were in Busan at that time. Anyways, I have a meeting with him tomorrow so hope we'll find out something."
"Okay then. I think we've done enough for today."
"I should get going in that case."
"Have you forgotten to tell me something Y/N?" Namjoon raised an eyebrow, a suspicious expression forming on his face.
"I think not." I shrugged my shoulders while packing my bag.
"I know you're dating Taehyung Y/N."
"W-What? How??"
"The chief inspector told us."
"What do you mean US? Who else knows?"
"Everyone! You are the topic of the day!"
"Ugh, this is why I keep my life outside work private. I hate everyone sticking their noses in someone else's business."
"I know Y/N, I know. Anyways, now that the two of you are dating, there's a promise that needs to be kept."
"Don't worry, I didn't forget. In fact, we can go now if you don't have any plans."
"Yeah sure! Even if I had any, I'd cancel them for free drinks!" he said making me laugh.
"Okay then, grab your stuff and let's go!"
"Will Taehyung be there too?"
"Uhmm, we haven't texted each other today so I bet he had a busy day. It's my turn to pay anyways since he paid last time." I said as we were walking down the stairs.
"Oh! It's Taehyung!" Namjoon said surprised as we got outside of the building and saw Taehyung leaned on his car.
Taehyung put down his phone and saw Namjoon waving at him, but as the two of us locked eyes, a rather confused expression formed on his face.
"What brings you here Taehyung?" Namjoon asked.
"I came to pick up Y/N from work." he said looking into my eyes, the tone of his voice low and slightly intimidating.
"And where were you two headed to?" he then asked.
"To grab a beer! Since you and Y/N are officially a couple, she said she'll treat me tonight because we made a promise last time."
"Oh yeah... the promise..."
"Join us! Y/N said you were busy today so she didn't want to bother you but I'm really glad that you're here so we can all celebrate together!"
"Busy?" Taehyung's brows furrowed.
"You h-haven't texted m-me at all today so I assumed that."
"Yeah I was busy but that doesn't mean I don't have time for my girlfriend after work. Lead the way Namjoon."
"Yes! Let's gooo!" Namjoon said jumping excitedly as Taehyung grabbed me by my waist and pulled me close to him.
"I have limits Y/N." he whispered in my ear, sending cold shivers down my spine.
