Author's Note: Hello to you all. This is my first Haikyuu fanfic and I'm really excited for it! I only started watching Haikyuu this year and I'm already addicted. I mean how can I not?!

This chapter is from Atsumu's POV. Enjoy!

Warning: The timeline of the story is after the last arc. So, to anyone who doesn't read the manga: SPOILER ALERT!

Disclaimer: Haikyuu! belongs to Haruichi Furudate.

It all started with a hickey.

If truth was to be told, Atsumu hadn't even noticed it at first until Inunaki suddenly pointed out with a surprised gasp, "Bokuto, is that a hickey?" The MSBY Black Jackals were in the middle of practice, Atsumu working on their fast attack with Hinata. This unexpected exclaimation certainly took everyone by surprise, most of all the addressed man who was practicing his serves. All eyes turned towards the said man and a collective wheeze was heard in the gymnasium when the accused hickey was finally discovered on his neck, just below the pulse.

"It is a hickey!" Atsumu almost yelled, pointing his index finger accusingly towards the outside hitter, "where the hell did ya get a hickey?!"

Everyone stopped what they were doing, their curious eyes fixed on Bokuto who was looking equal part shocked and afraid by the sudden unfolding of drama. Even Sakusa Kiyoomi, the infinitely antisocial Sakusa Kiyoomi, stood up from the floor where he was warming up with his freaky wrists to come closer to the pandemonium.

"Atsumu-san," Atsumu heard Hinata's unsure voice beside him, "What's a hickey?"

Atsumu stared at the orange haired boy, not exactly sure how to react. Hinata looked back at him expectantly, innocence evident in his big amber eyes. The setter almost felt guilty for discussinh such matters in front of him. Almost. Right now he could not care less since Bokuto freaking Koutarou, the biggest goof in the planet of Earth, followed closely by his "pupil" Hinata, had somehow earned himself a hickey. How?

"I-It's not a hickey!" Bokuto exclaimed defensively, covering the "not-hickey" with his palm. The whole scene would have been more believable if only Bokuto didn't stutter and his face was not of the colour of a tomato.

"Sure looks like one." Sakusa remarked casually as if not at all shocked by the wild romantic endeavours of the biggest baby of Jackals. Atsumu looked at the man incredulously, then smirked.

"As if ya know what a hickey looks like, Omi-kun."

"Huh?" Sakusa glared at him with his signature scowl, "I know more than you do."

"How?" Atsumu bared his teeth in a wide smile, knowing fully well how to push the buttons of the Itachiyama alumnus. "Ya can't even high-five people."

Sakusa's glare darkened, and for a second Atsumu felt it was mistake to push too much and he would have if only he wasn't having so much fun bullying Sakusa. Hinata looked between worriedly, trying to say something and then stopping. The little man did not want himself in the midst of the verbal brawl.

"I don't want this attitude from a man who couldn't score a since service ace during the last match." Now it was Sakusa's turn to smirk, his lips curling upwards in an arrogant manner as the setter's face turned red.

"Shut yer trap—"

"Will both of you shut up?" Adirah snapped, his eyes gleaming with mischief as he gestured at Bokuto, "We have more important matters to look into."

Atsumu realized with a start that it was true. He had been distracted, cursing himself and Sakusa, mostly Sakusa, for causing so. He glared at the germophobe one last time before turning his attention back to Bokuto who was looking like he would start running at an opportunity.

"Really, Bokuto, where did you get that hickey?" Inunaki asked with real curiosity, "Do you have a girlfriend?"

"No!" Bokuto screeched, stretching his arms out defensively as his shook his head with vigorous speed. The action did nothing but expose the much-discussed wound. "I'm telling you guys it's not a hickey!"

"Guys," Hinata sounded confused. And impatient. "What is a hickey?"

"It is not a hickey!" Bokuto cried.

"Then what is it?" Adirah spoke up, wriggling his eyebrows as if he won the argument — which he did. Supposedly.

Twenty pairs of eyes stared at Bokuto, demanding answers. "It's... It's nothing really really!"

Lame. That was what each and everyone's expression said.

"I-I fell from my bed this morning!" Bokuto yelled, covering his face with his hands in embarrassment. Everyone kept staring at him for a whole thirty seconds, then the entire gymnasium roared with laughter. Everyone laughed including Bokuto, who joined the party with hesitant chuckle which soon turned into his usual guffaw. Except Atsumu, who did not buy the explanation and was ready to bet Osamu's life on it, and Sakusa, who also did not laugh but rather continued his judgemental stare on Bokuto.

'Is Omi-Omi suspicious too?' Or not. There was the huge probability that Sakusa was physically incapable of stretching the muscles of his face to form a simple grin, let alone a laughter.

When the huffing, snorting and chortling of his gullible team subsided, Atsumu narrowed his eyes at Bokuto. "How do ya get a wound there from falling off the bed, Bokkun?"

Bokuto stilled, then laughed. "I sleep weird, Tsum-Tsum!" He scratched the back of his head in an adorable manner. "Don't worry so much about it!"

"But—"

"Let it go, Atsumu," Meian said in his captain's voice, and Atsumu shut up immediately. He respected his captain a great deal. "Everyone, get back to practice. Coach is going to really angry if he hears about this mayhem."

Scattered chatterings were heard before everyone returned back to their practices, only Atsumu, Sakusa and Hinata stayed where they were, looking out of the corner of their eyes to see Bokuto practicing his jump serves. He seemed completely in his zone by the third serve, his well-crafted form in the air to hit the ball with power and accuracy.

"He was lying, ya know." Atsumu said to no one in particular, his eyes never leaving the owl-loving man. He was pleasantly surprised when he heard Sakusa's affirmative hum in reply.

"Why do think he's lying, Atsumu-san?" Hinata asked, glancing at his mentor. Puzzlement was written clearly on his tanned face, and Atsumu could not blame him. Hinata was all sunshine and volleyball, and the setter doubted if the younger man had ever paid attention to anything except volleyball. He was like that just as his rival, Kageyama, who Atsumu could bet, had nothing in his head besides volleyball.

"Because that was a clear hickey," To Atsumu's utter surprise, it was Sakusa who answered. "And even if Bokuto really fell from bed, there is no way he could get a wound there. And if he really sleeps weird, then he must fall from the bed quite often. And if he really falls from the bed quite often, then he would have been wounded a number of times in that particular area too. And if he did, you," Sakusa pointed at Hinata, "must have noticed since you are bouncing on his shoulders every day."

Atsumu gaped, his jaw wide open while the ginger was nodding his head understandingly. Hinata looked up at Sakusa and practically beamed. "Wow, Omi-san, I didn't know you pay so much attention to us!"

Sakusa's ears turned pink. He coughed, opened his mouth to say something, then decided against it. Atsumu decided to put the poor bastard out of his misery. "Okay, so now that we know Bokkun is lying, we gotta figure out how we're gonna find the mystery person who gave Bokkun the hickey."

Hinata nodded his head enthusiastically, his eyes gleaming with the excitement of approaching adventure. Sakusa, on the other hand, looked positively disinterested. "Don't count me in."

"Huh? Why?!"

"I am not going waste my time on," Sakusa gestured vaguely with his hand, "this."

Atsumu raised his eyebrow at that, returning the same gesture in the air. "And what's 'this'?"

"Waste of time."

Veins were twitching on Atsumu's forehead. "Ya said that before," Why were people so bothersome around him? Taking a deep breath, mainly to control his urge to strangle someone, the blonde setter began again. "Come on, Omi-Omi, it'll be fun!"

Sakusa did not deemed it necessary enough to reply. He merely stared at him.

"Don't ya want to know who's Bokkun been hiding?" Atsumu pointed discretely at Bokuto, "Bokkun who shares every fucking little thing like what he had for breakfast or how he got to see an owl at the park, is hiding something this big. I mean someone actually gave him a hickey!"

To Atsumu's absolute wonder and internal enjoyment, Sakusa puffed a defeated sigh and nodded. "Alright."

"Guys, just to let you know, I am in," Hinata let his presence known again in an uncertain voice, "but can I ask something first?"

"What is it, Shouyou-kun?"

"What the heck is a hickey?"
