It was dark and the full moon was out. It was a sign that werewolves had to transform in their form in order to survive and catch their pray. That's what yoongi did in order 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 adopt jungkook. He had to keep his secret away. He was afraid that jungkook will hate him

Yoongi pov

I was staring at at my window when my mother came and called me for breakfast. 
As a hybrid. I hide 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 until my best friend hosoek came and scream at  my ears

Goooooooodddddd morninigggggggggggg hyunggggggg hosoek scream

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 why I don't have a dad like everyone. I realised the reason behind my new brother 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 what was hosoek was saying. Hosoek is also a werewolf but jiwoo is an alpha and hosoek is an omega. I really like hosoek 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 because I am lonely and different and have no father.

Not so long 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 is 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 hope he doesn't hate me.

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

He gave me a hug and I hugged him back. I realised that jungkook isn't any person. He is special and brought happiness into 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 tramatize 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.

I promise mother I won't transform in front of him I said

Good yoonie. I hope you tired and hungry and also I'm gonna go make jungkook something to eat. Have a good sleep yoongi bear. I sent hosoek and jiwoo home ok I call you just now to eat

Ok mom  I come and eat bye mom

Bye yoonie

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

Sorry hyung.
