It was dark and the full moon was out. It was a sign that werewolves had to transform in their form to survive and catch their prey. That's what Yoongi did to survive.

Yoongi was a werewolf and tiger hybrid. He transforms into a werewolf when the moon is full. He was born as a werewolf and got bullied for being different. His mother, Min Yoonji, was a woman who looked after him as he had no father. When his mother adopts Jungkook. He had to keep his secret away. He was afraid that Jungkook would hate him

Yoongi pov

I was staring at my window when my mother came and called me for breakfast. 
As a hybrid. I hid my tiger ears and tail, but my wolf instinct was calling me for a mate. I mean being bullied for being a werewolf. It's not. My fault I was born this way. Anyway, my mother went to the social service as I'm getting a new brother. I hope he doesn't get scared of me being a monster.

I was about to sleep when my best friend Hosoek came and screamed in  my ears

” Good morning Hyung," Hosoek screams, which annoyed me.

"Yeah, Hosoek, what do you want? Can't you see I want to sleep, and why did you disturb it? "

Sorry hyung, I'm sorry for troubling you, but your mom wants me to be with you. I told Jiwoo I'm gonna meet you, and she said ok, but the problem is she is also here.

Ok, why don't you call her? I want to see her.

Jiwoo and Hosoek are siblings and friends with me. I don't have any siblings I don't know why. I also don't know why my mother doesn't want to tell me about my father. It's not fair that I don't have a dad like everyone. I realized the reason behind my new brother's parents. They must have died. I heard that my brother is a Jeon, but he looks sweet.

I was deep in thought and didn't pay attention to what he was saying. Hosoek is also a werewolf, but Jiwoo is an alpha, and Hosoek is an omega. I really like Hosoek's wolf as his wolf is sweet and gentle like him. I feel like my form is cold and scary. No matter why I get bullied I am lonely and different and have no father.

Not so long ago my mother came in with a young boy.

Good morning, Yoonie. I want you to meet Jungkook. He will be your new brother. Jungkook, this is Yoongi, your older brother. He will look after you and protect you.

I looked at Jungkook, and he was really cute. I really want to protect him and hug him and the only way is to hide my inner wolf.
I didn't want Jungkook to be afraid, and I hoped he didn't hate me.

Don't worry about Jungkook I protect you and treat you. I said In a soft Tone.

He gave me a hug and I hugged him back. I realized that Jungkook isn't any person. He is special and brought happiness to me. I'm grateful for him

I thank my mother.
Mom thank you for being something special for me.

It's ok yoonie. I just wanted to make you happy as you suffered without your dad and getting bullied In school.

Mom, can I ask you something?

Sure honey what is it she asked

Mom, what happened to Dad, and why isn't he here? Is he gone I feel lonely mom

Yoonji felt tears calming. She didn't want to traumatize him. She didn't want to tell Yoongi that he died fighting in a war with the vampire hunter.  She doesn't want to tell Yoongi that he saw what happened. Yoongi was 5 when he witnessed the killing of his father. He was still young.

"Yoonie, I'm sorry, but it's hard. Just be happy, please. For jungkook. Please. He will make you happy. Can you promise me you won't transform near him, ok honey?" Mrs Min put her hand on the pale boy's shoulder as tears started to gather.

I promise my Mother I won't transform in front of him I said

Good yoonie. I hope you are tired and hungry, and also, I'm gonna go make jungkook something to eat. Have a good sleep, Yoongi Bear. I sent Hosoek and Ji Woo home ok I called you just now to eat

"Ok Mom  I come and eat bye Mom," I said as she closed the door

"Bye, Yoonie," I heard her reply, as well as my two annoying friends.

"Bye hyunggggggg"
Yeah hosoek don't scream like that you're gonna scare little jungkook. I said

Sorry hyung.
