Yoongi found you sitting in front of the laptop typing away when he returned from dinner. The sight immediately made him frown, realizing you were still wearing the clothes he had brought you earlier that day.

You didn't even bother acknowledging his presence, making his eye twitch. You were clueless to his irritation, your face glowing because of the light of your screen. However, that didn't last long as a hand closed the laptop, making you look up for the first time in surprise and complaint.

"Wh—" you stop, your eyes widening a fraction as you realize for the first time Yoongi had returned to the room the two of you shared.

"Did you shower?"

Your eyebrows furrowed in confusion at Yoongi's words as well as the growl he used. You feel small under his dark gaze, the pale man before looking strikingly haunting with the way he stared down at you. He had gotten rid of his wig as soon as he stepped into the room, the makeup he had on already taken off as well. He no longer looked like Min Yoonji but your Min Yoongi, the surprisingly masculine man who was your boyfriend.

"W-What? Why are you asking me this, Yoongi? I have better things to do, and you won't guess what I found out toda-"

"So you're telling me that even after you entered a pond that's probably infested with bacteria and shit and you still haven't showered? It's been, what? Twelve hours or so since Im Nayeon's body was found?" Yoongi speaks slowly as if he's talking to a child, making you freeze as you realize he only spoke that way when he was pissed.

Why the fuck was he pissed?

Yoongi looks down at you with his jaw clenched, his lips pulled into a scowl, "Y/n, when was the last time you've eaten? Have you not eaten anything since last night?" The man questioned, staring into your face, carefully watching for any change of your expression.

At that moment you realized you did feel a gnawing emptiness in the pit of your stomach. You tried to think to the last time you consumed something, which made your face twist because you realized Yoongi was right. Yesterday nights dinner was the last time you even drank or ate something.

Seeing the realization in your eyes, Yoongi gritted his teeth and closed his eyes. "I can't fucking do this."

You look at the man in confusion not understanding his words. What did he mea-

"Have you looked yourself in the mirror, Y/N? You look like shit." Your mouth dropped open at Yoongi's blunt words, not expecting it to slap you right across the face.

You're about to defend yourself, but before you could, Yoongi continues. "You're getting fucking attached Y/N. And it's draining you. When was the last time you had a good night sleep? And don't you dare lie because I know you haven't with all the tossing and turning you do in your bed. These murders are literally driving you up the wall, and you yourself haven't even noticed it!" Yoongi begins his rant as he throws his hand up, "I'm watching as you hide those circles under your eyes with your concealer. I see you skipping out on eating, I see you sitting in front of the stupid computer for hours just gathering notes! I-"

"It's my fucking job! You should know that better than anyone else, Yoongi! This is your job as well!" You scream, cutting off the male. Your eyes are narrowed on him, your cheeks flushing at your outburst.

Yoongi's eyes hardened as he returns your glare, his usually pink lips turning pale as they thin. "I know it's my fucking job. But I'm not getting attached to it to the point that I'm risking my own health. I'm a professional that doesn't let my emotions get in the way."

His words felt like a jab straight to your heart. It hurt your pride. Fuck, it really did hurt your pride at what he hinted. He was implying you weren't being professional.

"What the fuck are you trying to say," you growled, standing up so you can adequately face the man in front of you, not willing to back down, especially when Yoongi was threatening your pride as an agent.

"You're getting emotional Y/N..." Yoongi's voice suddenly softened, the anger from earlier seeming to dissipate. The man released a sigh, running a frustrated hand through his locks of raven hair. "I see it in your eyes, you're letting your emotions control you. This is like any other job we had in the past, we can't let it control us if we want to complete this assignment. We need to find the killer, get him between bars and get out of here ASAP.  I know it's upsetting that these women are getting killed but-"

"That's the thing Yoongi! They're not even women yet! These are children, girls that have a long future ahead of them and they're getting killed by this psychopath! And we've been here for a while yet we haven't found a single thing that may link us back to the killer..." Your voice cracks near the end of your sentence, your eyes watering.

Yoongi's eyes soften as he steps forward, wrapping an arm around you and pressing your face to his shoulder.

"This is exactly what I mean... Your emotions are making you do things that are very unlike you....." The male mumbles as he places his lips on your temple. Yoongi knew how you were during missions. You always put one hundred percent to every assignment you are given, and you always did phenomenal in them. However, this case has been more complicated than what the two of you have been doing for the last couple of years.

He understood your point, he was also getting frustrated that neither of you has gotten any solid clues too. He knew that was one of the reasons why you were stressing, but at the same time, he also had an idea why it was making you emotional like this.

In the past assignments, you worked with the mafia and gang-related crimes, finding notorious serial killers, stopping illegal shipments, the list can go on forever. You even have dealt with human trafficking for very young children. But this was probably the first time you were working with crimes related to teenagers. And Yoongi knew teenagers were a touchy subject for you.

"Y/n, this is what I think..." Yoongi speaks gently as places his chin on your head. "You're getting emotional because these girls are around the same age as B/N when he was killed. You're overlapping the image of your brother with these girls... You can't do that, you need to have a clear mind or I can't trust you as my partner," Yoongi speaks although he knows his words are harsh.

He knew how much your brother's death affected you. However, he couldn't risk you or his safety if you became emotional and made risky decisions that could jeopardize this mission. He was almost tempted to send a message to Mr. Bang and Namjoon, requesting for them to pull you out from this mission and replace you with someone else if you didn't get your shit together.

"And if you really want to catch the killer, you need to take care of yourself first. What makes you think you can save someone else when you can't even look after yourself?" Yoongi questioned as he pulled away from you, using his sleeve to wipe your face, "and it makes me worried when you don't eat..." He weakly adds, his cheeks flushing slightly at what he admitted.

It was a habit you had that constantly worried Yoongi. It wasn't unusual for you to lose track of the things around you and not take care of yourself when it's related to work. Yoongi knew that first handily because he experienced it when you had gone undercover for a solo mission and didn't message him for a whole week, much to his horror. He was worried sick to the point where he threatened Namjoon to reveal your coordinates so he personally could make sure you were alive by flying over to where you were.

He didn't, thank god.

You laughed weakly and sniffled. You hated to admit it, but Yoongi was right. You usually didn't get emotional for missions. But this one was especially hard for you to not. And hearing Yoongi's explanation, it did make sense. If you really thought about it, you've brooded about B/N more time in the last few weeks than the time you spend as an agent for BigHit which was much longer than a handful of years.

"I'm sorry, Yoongi. I was at wrong..." You grumbled, irritated that Yoongi was right once again. Honestly, when was he ever not right? "I'll take care of myself more and concentrate on our mission..." You pushed your stupid pride to the side and apologized. However, at that moment, you remembered what had happened earlier that day between the two of you.

Okay, so you understand why Yoongi was mad at you. But that doesn't justify and explain the cold attitude he showed towards you when you were with Jungkook and Taehyung. Even the younger boys noticed it and questioned it. And this was the perfect timing to question it.

Yoongi's eyes widened, his mouth parting in surprise as you suddenly pushed him down, his body bouncing as it landed on his bed. His hands subconsciously moved to your waist as you sat on his stomach, looking down at him with a frown.

"Okay, now that you're no longer mad at me, can you explain the attitude you had today?" You questioned, raising an eyebrow up as you stared down at your man.

Yoongi doesn't even have to think hard to know what you mean. Of course, he knows, he had acted cold on purpose. However, he acts clueless as he frowns, narrowing his eyes at you. "I don't understand what you mean," he grumbles as his hand slide up under your shirt, feeling the soft skin of your hips with his palm.

You scoff, quickly seeing that he's lying with the certain way his dark eyes gleam. To add on, the way he was touching you obviously meant he was trying to distract you.

Oh, no he wasn't going to succeed. You were going to interrogate him until he spills the beans and tells you exactly what you want to hear.

Your hands grasp his, stopping their movement as you looked down at Yoongi with a frown.

"Don't you try to play sly, mister. I know exactly what you're trying to do. Now tell me, why were you so cold to me, your girlfriend today?" You questioned in amusement, making your voice few octaves higher than usual. You give your boyfriend a pout, which makes the said man roll his eyes, scrunching his nose in disgust.

"Ew, don't use aegyo on me, gross," Yoongi gagged making you laugh and shove him lightly. With that, the dark haired male breaks into a gummy smile that makes your stomach feel warm and fuzzy.

Yoongi quickly sits up, one of his arms lazily wrapped around your waist as he places his lips against your neck, giving the soft flesh teasing nibbles.

Oh, he really was trying to distract you now.

"Yoongi....." You whined, tugging the male off of you by grabbing his hair, gently pulling the soft dark strands.

Yoongi groaned as a scowl was placed on his face as he sent you a light glare. "You, woman, were the one being cold in the beginning making all those ridiculous rules of no skinship," the man pouts childishly making you break into a smile of victory.

"Ha! I knew you were acting cold! Now tell me why!" You demand, making faces at Yoongi.

In response Yoongi's cheeks flushed, a look of embarrassment spreading across his features. At first, he mumbles something. But it's barely audible, making you tilt your head to the side in confusion.

"What did you say?"

Yoongi repeats something, this time you being able to hear it better. You get the gist of it, but you're feeling mischievous, wanting to Yoongi to say it in a normal tone.

"Repeat that?"

Yoongi groans as he buries his face into your neck, his warm breath fanning against the skin making goosebumps rise on your arms.

"I said I don't like these brats hanging off of you. Especially that Sungwoon kid, having the nerve of offering you his jacket. And then there's the flower boy and fucking playboy. And I'm sure there's more...." Yoongi scowls, avoiding looking into your eyes.

You giggle at his childishness and cup his cheeks, giving him a teasing smile. "Aw, is my Yoongles being jealous of teenage boys....?" You cooed as you babyfied your voice.

The blush on Yoongi's cheeks gets more profound as he refuses to look at your face. "Shut up..."

"Awww, I love you, Yoongi. You know that!" You laugh as you cup both his cheeks with your palm, planting a kiss on his lips.

He immediately melts, one of his hand moving to the back of your head, tilting you in a way so he could deepen the kiss. He placed his forehead against yours as you both pulled away, his dark eyes giving you a questioning stare, the corner of his lips tilted up to a smirk.

"What happened to the ban of no physical contact with each other until the end of the mission?" Yoongi questioned slyly.

You groan before tilting your head, chasing after his lips, which he doesn't deny.

"Let's just forget about it for now?"

"Agreed."
