Prince Oikawa Tōru + Prince Oikawa Reader (x Ushijima Wakatoshi)

The brothers fight before Reader leaves for war.
*********
"That's not how princes behave, Tōru." The older Oikawa crossed his arms as the young prince copied him, "Well maybe you should stop criticizing me!" He slouched in his chair as (Y/N) sighed, "I wouldn't criticize you if you just acted proper!" "Well maybe I don't want to be a damn snob!" He slammed his hands on the table, "Don't raise your voice, Tōru." "Fuck you!" The dining room fell silent, the servants not daring to move as the younger realized what he said, "I'll be in my quarters if anyone shall need me." The older prince stood from his chair, clapping his hands for the servants to clean up. They opened the double doors as he walked out, closing it behind him and leaving Tōru by himself.

The brothers never talk after that, (Y/N) was sent to war only a couple days after the fight. The years flying bye as Tōru's regrets caught up to him, the crown being placed on his head as he was declared king of the kingdom. 'It was supposed to be you,' He wasn't the oldest son, he wasn't supposed to be crowned king, (Y/N) was. He was the eldest son, better at being a king than Tōru ever could. The crown didn't belong to him. It was a fake. But he could only except it, praying to the gods above that it was a terrible dream and that he would wake up with his big brother. He closed his eyes and took a deep breath, opening them as he saw the guests leaving. He got up, walking towards his room. Tomorrow was his first king duty.

The carriage came to a stop as the reins snapped against the horses, a servant opening the door for Tōru. He stepped out, tipping his crown at the servant and making his way towards the palace doors. The wind sent a chill up his spine, the doors to his new friends. The peace treaty would be signed today, no more wars would happen between the kingdoms as the finally unite. He was lead through the main hall to the treaty room, many kings and queens seated around the table. He took a seat, greeting some of the others as they greeted him, the meeting beginning. Wakatoshi stood up first, "Thank you for coming, I hope we can come to an agreement."

He bowed a little, "Now, (Y/N), my husband and king alongside me, will start." Tōru's eyes grew wide, looking towards Wakatoshi and seeing (Y/N)- his brother- standing beside Wakatoshi. His heart quickened as all the memories came back to him, barely able to hold it together as he watched him. The war changed him; a visible scar from underneath his shirt stopped at his chin, he was more monotone than Tōru remembers, but his eyes still had the same (Y/N) he knew. He watched as he sat down, a paper being placed in front of him. He missed the speech, too focused on not jumping up and telling (Y/N) how much he missed him and how sorry he was.

He wished he could take that day back, but he knows he can't. 'Maybe he hates you,' He thought, his shaking hand holding the pen. He glanced up, seeing how (Y/N) looked so different, not believing it was actually his brother. Tōru thought he was dead, slain in battle to protect the kingdom, but here he is. Tōru has never been so glad he was wrong, now knowing he had a chance to un-fuck things up. He signed the paper, placing the pen back into the ink bottle and interlocked his fingers. 'Soon,' He thought, soon he'll be able to talk to his brother again. The treaty signing ended early, the kings and queens getting in their carriages. Tōru turned, surprised to already see (Y/N) and Wakatoshi behind him.

His heart pounded in his ears, the feeling of vomit making its way into his system, "Tōru," (Y/N) softly spook, "I missed you," He smiled. Tōru let the tears run down his face as he pulled (Y/N) towards him, feeling his brother hug him back just as tight.
