Mine and Only [AU ; Soukoku]

How it started

Dazai Osamu was walking down the street calmly with his usual crutch under his right arm, his eye all bandaged up and his arms and neck wrapped in bandages as well.
The little Dazai ignored the people staring at him and whispering at each and continue walking. Even before the accident, the accident that left Dazai very hurt physical and mentally, nobody at the neighbored liked Osamu, the boy with a sadistic smile and was given the nickname the heartless dog. Dazai's bad fame spread even more when on his parents funeral he didn't shed a single tear. His grandparents, who toke him on their home, loved him very much and support him but Osamu only with 10 years old was more independent and responsible than a teenager or a young adult. He was a prodigy and could quickly read people's behavior making the people of the town being more frighten by him.
This particular day Dazai was walking back home, not going on the school bus like a normal child would do. He hated his class mates not because they hate him too but because they were just... Too dumb and naive. Dazai didn't like those kind of people. He walk trough the side walk careless and looking around with his big and chestnut eyes, glowing softly at the daylight. He soon arrived home and walk inside, placing his back pack at the wooden floor and walk to the living room, his crutch producing noises everytime it hit the wooden floor. He tense soon he saw people, people he didn't knew at the couch.
"Who are you?" Dazai asked almost immediately and walked closer to them. The couple looked to the boy and smiled.
"This must be the petite Dazai~" The woman spoke with a strong french accent and Dazai tilt his head curiously like a little bird. Then he saw his grandmother coming back and petting Dazai's hair, taking him to the couch. Osamu sits down and watches his grandmother speaking with, apparently, the new neighbors next door.
The men stand up and went to the back yard leaving his wife alone. Dazai waggle his good leg softly, looking to his grandparents. They also had a son, at age ten as well. Soon he heard this information, he grabbed his crutch and walked outside. He saw the men trying to take his son to inside but he could see how shy he was. He look to the door and soon he saw Dazai he hide behind his father's legs. The brunette smiled, making the boy even more uncomfortable, he looked down making his ginger locks of hair covering his eyes. His father walk back inside deciding leaving the boys alone to meet. Dazai walked closer to the boy who placed his hands behind his back.
"What's your name?"
"Chuuya... Nakahara Chuuya. And your's?"
"Dazai Osamu~" The brunette raised his hand to greet him "It's a pleasure to meet you, it looks like we are going to be neighbors"
The ginger one looked to his hand and smiled shyly, shaking his hand kindly. It's was the first time someone ever had come to him and act so friendly. Chuuya smiled genuinely and let go his hand, Dazai smiling softly to him as well. The ginger one knew something 'clicked' between them and he was excited to get to know the brunette better. Very excited.

Hours later Chuuya's parents were looking for his son on the house along with Dazai's grandparents. They found the boys on Dazai's bed sleeping together, both tired from pillow fighting board games and their bellies filled with chocolate from Osamu's secret storage in the room.
The mom couldn't help and smile widely, seeing that his son had finally made a friend. His first friend. She pick him carefully but he woke up anyways and blinked, still very sleepy. He lean his head on his mother chest and yawned softly, looking to his sleepy friend. He heard his parents talking to his friend's grandparents but he was too tired to listen. His eyes didn't move from Dazai. He smiled as the memories from the day crossed his mind.
When Dazai toke him to his room to play with him, tease him about his hight specially making the small Chuuya hit him from the first time. Which made Dazai laugh for the first time. The moment when Dazai opened a secret storage behind his bed, a secret hide out on the floor full with candy and he gladly shared with Chuuya. The memories of all the game they played come to him making him smile wider. He never had such fun in one day before. Never.
He closed his eyes again and nuzzled his head on his mother's hair contently. Not even noticing the small Dazai already awoke and out of the bed. He poked the women's leg with his small finger, calling her attention.
"When can Chuuya-kun come back?~"
Nakahara's mother smiled and petted his head, saying that Dazai could visit Chuuya anytime, since their houses were side by side. His grandparents also added that Chuuya was always welcome here. The couple soon left with their sleepy son on the mother's arms and Dazai stayed by his window watching his new friend disappearing when he entered his new house, right next to Osamu's.

The next days passed flying. Chuuya was transferred to his class and Dazai was in charge to show him the school and tell him the rules, since in France the costumes were different. They played together in every recess and walk back home together everyday. Soon Chuuya realized why Dazai didn't had any friends besides him. But he didn't care. He liked Dazai and Dazai liked him. What could possibly go wrong? Besides their friendship become even stronger when Dazai realized why Chuuya didn't had friends. He was an ability user, he could control gravity of himself and everything he touches. He was called a freak and many other names that when Chuuya finished telling his tragic story he couldn't resist and hugged the ginger one. Nakahara never though he would be able to trust other person again by telling he was gifted, he never felt so happy in his life. He knew Dazai would be a very important person on his life and Dazai could felt the same. They were meant to be friends and  even more. They just didn't know yet.
