Siblings Bonding (Various Anime Characters! *Brother /Sister* X Reader)

When you two met after being separated for 11 years. (Shidou Hikaru X Reader)

Flashback to 11 years ago

You and your brother Shindou Hikaru were playing happily with each other around the garden. 

"Onisan...onisan...haha...." You giggled as you run to your big brother.

"Come on, imotou...Let's play!" Hikaru said while pulling my hand.

"Hiak....onisan."

Laughter can be heard around the garden. You both were playing happily but however you both didn't know that something is going to happen.

" Our son and daughter are just so close, but one of them have to be given to someone else." Okasan sighed and tears welled up in her eyes.

"Don't worry dear. (First name) is only two and Hikaru is only three. They would not know anything." Otosan hugged her and comforted her.

"But I don't want to be separated from any one of them."

"Dear, I promise you that when we are rich we will get (First name) back."

"What? You are going to give (First name) away? No way! She is just two years old.

"She will be the best to be given to someone else."

Tears rolled down to your mother's cheeks. You can feel a bitterness of the mother who needs to leave her child to another parent. The next morning, a young couple came and took you away and before you knew it you were brought into the car.

"Onisan....onisan...." you cried for Hikaru, as you looked through the car window.

"Imotou! Imotou!" Hikaru rans and chase the car.

He ran while showing the bracelet that we made during our art class in the free nursery in our little town. That's the promise that we made that we will never forget each other and we will meet again. Okasan and otosan waved you goodbye. They were very sorry that you have to go through this. Hikaru on the other hand throws a fit saying the three words "I hate you" to Okasan and Otosan and for three months he didn't have the appetite to eat. He went inside your room and cry. He saw your things and began to take it and hug it tightly and imagine that you were there beside him.

Meanwhile in the young couple's house, when you just stepped in you feel something tingling which made you froze up. It was your adoptive mother who was giving a fiery glare. You smiled fakely as you were shivering with fear.

"Now, little girl! You need to do as I say, okay! My house my rules! Got it?"

"Okay!" You smiled but you were still sad that you were apart from your family.

"First, I want you to bring me a book and later help me to massage my back. Pick some flowers and teach Yuuta how to read!"
