The war between two kingdoms was soon to end, an arranged marriage, saving them both from a dreadfully long painful rivalry. While one rivalry ends, slowly simmering is another between the twin princes. Bitterness is heavy in Atsumu’s throat after hearing that Osamu will be taking the throne to rule, apparently madly in love with the rival prince.
He can feel happiness for his brother but watching the dream he has worked so hard for crumble in front of his eyes is heartbreaking. The dream he has had since a little boy, the stories of how his father ruled with a great knight who was always by his side. That knight was Bokuto Koutarou’s father, a great man who sacrificed his life to save the King. Of course Atsumu wanted to honor the man who had saved his father by making his right hand man Koutarou.
Koutarou had grown up in the castle alongside the twin princes, his mother tended to the boys and they were close. Over the years Bokuto began intense training to be a great knight just like his father and soon became closer with Atsumu. Where the prince was meant to be proper and classy, with Bo he never had to pretend but just be himself.
Bokuto had grown to become a handsome young man, often getting mistaken for a royal himself. The blonde always loved the way he looked in his chainmail and armor that shined like the stars but his favorite is when the knight is dressed down in his linens. The creamy fabric rests so nicely against the man’s broad chest and large arms. The prince twiddles the hem of the neckline in his fingers, laying next to the older.
“I just can't believe that ‘Samu never trusted me enough to tell me he was secretly in love.” The younger pouts, finally meeting the golden orbs that are staring directly at him.
“Maybe he was too scared, maybe to even speak the words would make his whole world crumble.” Bokuto hums and pushes some hair out of the other’s eyes.
“Well while trying to not let his world crumble, he definitely let mine.” Atsumu’s pout gets bigger, eyebrows furrows deep.
Koutarou clicks his tongue before springing out of his bed, grabbing the prince’s hand and pulling him out of the room. Atsumu is sputtering a string of questions but the older one ignores him as they make their way up one of the watchtowers. Soon the blonde’s voice is stuck in his throat as he looks up. The midnight sky is decorated beautifully with twinkling stars.
“You might not become the king of the two kingdoms before us, but you could be king of the world.” Koutarou whispers, breath hot against the shell of Atsumu’s ear.
A shiver runs up the younger’s spine as he looks across the different twinkling dots above them. Bokuto always had a way of keeping the prince at ease, this time is no different. Atsumu turns to face the older, his golden orbs shine so brightly. It's almost instinctual the way he closes the distance, bringing their lips together. It tastes so sweet, shooting off endorphins in the blonde's brain.
Koutarou takes a step back, eyes wide and cheeks pink. The prince thinks he has messed up and goes to apologize but the knight brings their lips back together for another searing kiss. Atsumu wraps his arms around Bokuto’s neck and pulls them closer together. The world feels completely frozen, as if they are the only two to ever exist. Bo keeps the pace soft and steady, lightly nibbling at the bottom lip of the other.
Atsumu’s heart rattles in his chest and there is a fiery pit growing in his stomach. They kiss longer than the last, as if they could never stop. Soon the two pull back for air and the blonde is struggling to find his breath when he is looking into the gold eyes looking at him with a slight hunger. Goosebumps start to cover his body, the light breeze goes through the older’s hair, making him look like a walking dream.
“May we go back inside and continue?” The younger asks with a soft voice.
Kou nods and follows the prince’s lead, down the stairs and to the latter’s room. The knight tries his best to avoid eye contact with the two guards outside the door. Once in the room, Atsumu pulls the older to land on the bed. The royal decides right then and there that is where Bokuto belongs.
“I’ve wanted to kiss you for a very long time.” He hums as he crawls on top of the other.
“Really?” Bo asks perplexed, a pink tone settling on his chest as he ghosts his hands on the prince’s thighs.
“Of course, have you seen yerself?” Atsumu cocks his head to the side, electricity running through his veins.
“You are sculpted with so much muscle and yer eyes look like the sun as it sets on the horizon.” He runs his fingers over Kou’s biceps.
“You think of me like that?” The confused expression deepens on Bokuto’s face.
“I think ‘bout you in a plethora of ways.” The blonde taps Koutarou’s jaw with his finger.
Before the other can respond, Atsumu is kissing him. Bokuto accepts it easily and matches the pace that the younger sets. Kissing his knight is now the prince’s favorite thing, practically melting into Bo’s body as the latter slides his tongue against the roof of his mouth. The fire that was growing in the blonde’s stomach spreads all over his body in waves of pleasure.
The heir thinks to himself that if his brother can choose love then maybe so can he. Maybe he can now live his life with the one he has always wanted all to himself. There is no responsibility for him if he doesn’t want it he assumes, all of that falling on his twin. Maybe it was a gift rather than a curse.
“I want to be with you.” Atsumu breaks the kiss to make the breathless declaration.
“With me how?” Koutarou keeps steady eye contact, his hands roaming higher up the other’s thighs.
“I want to be with you, follow you till the ends of the earth.” The blonde purses his lip into a pout as he talks.
“I’ve always vowed to be by your side ‘Tsumu.” Kou smiles brightly and kisses the pout, catching the prince by surprise.
The kisses lead away from Atsumu’s lips and down his jaw, each touch of the older’s lips feel like the sear of a brand on his skin. They are so close but the prince wants to be closer, tugging at the shirt that covers the skin he wants to feel against his. Bokuto gets the memo and pulls back to pull the linen shirt over his head, tossing it on the ground. ‘Tsumu smiles and does the same with his shirt, eyes taking in how gorgeous the other’s torso is.
“So, so pretty.” He whispers under his breath and runs his hand up Bo’s abdomen
“Coming from the most ethereal person in this castle.” Koutarou clicks his tongue, hands on the blonde’s sides.
Desperately the prince brings the knight into another kiss, chest blooming as he tastes the saccharine of the other on his tongue. Even if the future is unknown, the sake of the kingdom out of his hands and shoved away to someone else, he has his knight. Koutarou vows himself to him, so he will do the same.
They spend the night in each other’s embrace, soft touches and kisses explore one another's bodies. Atsumu hopes that every night he can have the older like this, in his arms until he can no longer hold Kou. Promises are whispered between them as the morning sun rises, marking a new day of an in love prince and his faithful knight.
