(I have a thing for soulmate au's so there will probably be a lot of them lmao)
Your soulmates words are tattooed on you. Not their first words, nor their last, just a sentence they will say to you during your lifetimes.
Yamaguchi threw his hand out to stop the ball. Instead of flying up into the air like it would with everyone else, it ricocheted off his hands and flew out of the court. He let out a sigh.
He sucked at receives.
"You'll get better, freckles." Hinata reassured him. For a moment, Yamaguchi didn't even recognise those words as the ones that had been tattooed on his arm for 15 years. His reply came back without even thinking about it.
"You also have freckles." Yamaguchi reminded him as he picked up the ball and turned around to face him.
Though, he immediately dropped the ball as he felt a burning sensation ripple down his arm.
He clutched his arm where the words were burning, letting out a sharp yelp.
"Ow! What the-" Hinata had dropped to his knees, cradling his forearm. Yamaguchi fell too, falling backwards onto his arm. The burning was unbearable.
"What's wrong? Guys!" Sugawara asked, worry evident in his eyes.
"M-my arm!" Hinata shouted out. By now, Yamaguchi had closed his eyes tightly, tears threatening to pour.
He peeked his eye open. The whole team was surrounding them on the floor. Hinata had a few tears down his face too.
Yamaguchi felt arms land on his shoulders. Tsukki.
It felt like it lasted for hours. The burning began to subside, Yamaguchi's grip loosening on his own arm and he leaned backwards into his friend. Hinata had brought his knees up and was now resting his forehead there. Silence followed.
"Hinata." Yamaguchi said quietly. He opened his eyes to look at the boy who slowly raised his head. "Y-you know w-what this is, right?"
Hinata nodded, a small smile creeping on his face.
"YOU'RE MY SOULMATE!" He shouted, crawling over to Yamaguchi and tackling him onto the floor. He let out a soft oof, his back hitting the floor with Hinata's gleaming face right above him.
"Yeah." He let out a chuckle. Hinata's bright eyes burned into his and for a moment he forgot where he was- layed on the volleyball court with his entire team surrounding them. He could get lost in his brown eyes, and he suddenly began to see the spiker in a new light.
Yamaguchi sat up, causing Hinata to squeak, now sitting in his lap. Their faces were incredibly close together, Hinata could feel the taller's breath against his own lips.
"Uh, guys? Hate to interrupt the moment but we have training to do." Daichi's voice brought them back to reality. Both went red, pulling their faces away as Hinata clambered off his lap quickly and Yamaguchi stood up. Suga hit him on the shoulder, glaring at the captain.
"They just found out they were soulmates and you're stopping them to train?" He said incredulously.
"We have a match in a week. You can be lovey dovey after."
"Of course, sorry." Both of them bowed at 90 degrees.
--------
Exactly a week later, they were at the match. Yamaguchi waited in the sub box, as per usual, watching not the ball but one player in particular. Whenever Hinata caught his eye, number 10 blushed felt his insides flutter.
It was one of those moments where Hinata was caught off guard. He never was good at receives with his hands, often ending in him being hit in the face. This particular ball, served by Oikawa, hit him straight on the forehead, causing him to fall and hit his head on the floor. The court went silent, skipping a beat before Kageyama shouted.
"I think he passed out..." Yamaguchi was there in a second, the coaches following not far behind. Hinata blinked a bit, meeting eyes with his very concerned boyfriend. Hinata sat up, facing Yamaguchi, who opened his mouth to ask him something but was shushed by the smaller caressing his hair.
"Pretty..." He muttered. Yamaguchi blushed as a couple members snickered to themselves.
"Shouyou, do you know where we are?" Yamaguchi asked.
"Uhh... The gym floor." He said confidently.
"Whose gym floor?" Yamaguchi pressed.
"Huh? Our own? Are you stupid?" Yamaguchi rolled his eyes.
"I think he could have a concussion." He said to Takeda. "Should we take him to the nurse?" Takeda nodded.
"Hinata, can you stand?" Takeda asked. Without even trying, Hinata shook his head, staring at Yamaguchi.
"Pretty boy will have to carry me." He said, smiling brightly. The opposing team was waiting at the net, laughing a bit at Hinata.
"Fine. C'mere." Yamaguchi said. Hinata waited till he stood, then stuck his arms out like a child. Yamaguchi sighed, picking the shorter boy off the floor and carrying him bridal style. Hinata began to poke at the freckles on his face, causing Yamaguchi to wrinkle his nose.
Hinata suddenly moved his head up and kissed Yamaguchi.
Karasuno, who were used to them being together, shrugged it off. But Date tech all looked a bit shocked, especially when Hinata said "I love you," before resting his head on the others chest, and Yamaguchi's reply was a chuckle and then a kiss on the forehead.
"Love you too," he replied, walking out of the gym.
