Work Text:
Genya looked at white ceiling as he tossed and turned. Why can't he concentrate? School starts in an hour, hearing his brother running through the house searching for everything. No, he didn't feel like getting up. Placing the white pillow above him and loudly as screams escaped his mouth. he was drained from everything, at this moment he didn’t want to even go to school. Daylight shone through the window as he looked towards the door, seeing Giyuu standing with arms crossed. He laughed seeing the teen in bed tangled between the blankets.
“Your brother is gonna get mad.” He commented as he walked. “Come on.”
Genya groaned, “Tell him to let me stay.”
Giyuu laughed, grabbing the covers as the other fought back. “Why do you think he would listen to me?”
struggling to keep the sheets fisted the younger spoke, “Cause you’re his boyfriend and lived longer with him.”
“you're his brother, he loves and will listen if you tell him why.” Managing to grab the blanket off.
Genya pouted, sitting up, glaring at the man in front of him. the other continued to laugh at the reaction, he threw the blanket in his face. “Come on, breakfast is ready.”
putting on a hoodie and jeans on, running his hand through his mohawk, descending the stairs. The instant smell of food hit him as the voice of his brother filled the room who was happily humming something. walking in the kitchen, he was greeted as a plate was placed with his brother smiling.
“What is wrong with your face?” he questioned.
“can’t I be happy?” as he bites his toast. “It's a great morning and no you’re not staying home and happy birthday.”
“Come on.” Genya whined as Giyuu laughed.
sanemi's face softened, “Look Giyuu, My baby brother is officially seventeen.” As he wiped fake tears off his face.
It Brought some there the happiness of his brother being so excited for his brother. Sanemi ruffled the mohawked hair as he moved around the house gathering everything for work. They finally got ready and made the drive towards the school, the traffic dragged itself leaving only a few minutes between the bell. After the dreadful first four lessons, genya manged to drag himself off to his locker. Digging in the locker in search for his books for the next lesson after break. All Genya wanted to do was to scream into the locker however he stopped himself. The results wouldn't do anything hopeful.
A horn sound filled his ear directly making the Mohawk hair boy jump. Genya started swearing as his ear hurt.
“Happy birthday.” A ground screamed happily next to him.
The boy couldn't help but smile at the group. Tanjiro smiled brightly as Inosuke held the party horn between teeth, Nezuko held a box as Muichiro, Zenitsu held a paper with happy birthday written with coloured marker. A smile formed on Genya's face as he looked at his friends, all wearing smiles on their faces.
Tanjiro smiled brightly, “come on Genya.” He spoke. “We brought cupcakes to celebrate.”
Inosuke grabbed his arm, “Come on.” As he dragged Genya to an empty classroom as the rest followed. Cupcakes and drinks were placed on the tables as everyone gathered around the tables and chairs.
“I know it's not a lot.” Nezuko began, “but we can only do so much in school.”
Muichiro stood next to Genya, “Happy birthday.”
“Guys, it's great.” Genya thanked them. “Really thank you for everything.”
Inosuke glared at the Mohawked boy while his eyes moved to the cupcakes and back. Genya laughed, moving his hand to the cupcakes.
“Just eat Inosuke.”
The boy grinned as he bit the cupcake and everyone copied. Zenitsu patted Genya on his back, “anything planned?”
“No, don't think so.”
Muichiro commented, “You should go to an arcade.”
The taller boys laughed, “Yeah I don't think Nemi would allow me to. Purely since it's the middle of week.”
“Your brother sucks. More than my grumps.” Zenitsu groaned.
Genya snapped. “My Nii-chan is the nicest person in the world.”
Tanjiro stood between the two. “Calm down. It's all good here. Zenitsu stop making comments about Shinagawa- sensai.”
Nezuko hummed in agreement as Muichiro's eyes widen. “The arcade.”
Everyone looked confused. As Muichiro smiled, “We should go to the arcade on Saturday. Late birthday party.”
Inosuke began speaking as he was still eating, “Great Idea Huichiro.” The long haired boy titled his head as he corrected inosuke. The other just waved him off.
While Zenitsu had a disgusted look on his face, “Don't ever speak with your mouth full. It's making me gag.”
“What did you just say Monitsu?” As he grabbed his hair.
Everyone bursted into laughter at the interaction. Genya wasn't so angry he came to school anymore. It brought him joy to see his friends hanging around together. Every bad feeling escaped his body at the moment.
Standing outside the school as minutes passed by, wind brushing against his body waiting for his brother to finish his work. His friends had to leave the Mohawked boy alone. Normally Genya didn't mind however his phone died leaving him to listen to voice talking, wind hitting the building and listen to everything. Genya didn't enjoy this, he preferred listening to music.
“Come on.” His brother called out, holding a hand out.
The two got in the car and began their way to the house. The older man turned on the music as Genya grinned at him, Sanemi didn't like listening to music while driving but Genya guessed he did it purely for the younger to enjoy. Sanemi rolled his eyes at the gigantic smile on the face, he couldn't help but love the younger expression while he sung along to the songs. It made him cheerful, seeing his brother smile. Once they got home, sanemi told Genya to dress up because they were going somewhere together. He had everything planned out. Sanemi wanted him to have a good day, clearly it didn't begin like he wanted but it got better from the express the younger had. The smile upon his face that appeared once his friends came home in celebration at school.
Once they got out of the house and began walking down the street with the stars lighting up the dark sky, the moon was visible through the misty clouds. Street lamps cleared the pavement as Sanemi pushed open the door revealing everyone as they screamed happy birthday.
Their siblings ran towards Genya as they jumped, making him fall onto the ground, Sanemi bursted out laughing. After a while Genya stood and sprinted towards their mother who had a massive smile on her face.
“Mum.” Genya sobbed, “I thought you weren't gonna make it here.”
His mother ran a smooth hand through his dark hair, “I didn't think so. Sanemi and Giyuu helped, they didn't want us to miss your birthday.”
Genya grabbed his older brother from his siblings pulling him into a tight hug as the other dashed towards into the group hug. Everyone was eating and laughing having a good time, Giyuu was grabbed by their siblings who were braiding his hair.
“Thank you Nii-chan.” Genya spoke looking at Sanemi who laughed.
“Don't think you're special.” The white haired man grinned, “Besides she is my mum and siblings, I missed them.”
“I'll have to thank Giyuu as well soon.”
Sanemi nodded, “You know, he loves you as if you were his own brother. Remember he knew you first because of Kamado. I only started to know him after I passed my hatred towards him.”
“You never hated him.”
“No I don't think so, Obanai told me the exact same thing.” he recalled. “Apparently I never had that tone of hatred.”
After a while Sanemi hugged him tightly while rubbing his back. He could feel his brother quiet sobs as he was hugging him, his sobs escaping his mouth.
“My baby brother.” Sanemi cried, “Growing up. God damn it, I swear if you grow any taller I'll chop your legs off. And if you ever think about being a smartass to me, you will never see the daylight.”
“Nii-chan.” Genya smiled. “I'm not a baby.”
“Shut up.” He unhugged him as he looked into his eyes. “ You're always gonna be my baby brother. You were my first brother, so baby.”
“I love you.” Genya said. “You're the sweetest brother in the world.”
“Love you too.”
“Cake time.” Their mother called out bringing the cake forwards to the son. “Make a wish sweetheart.”
