psychological instability

I am the bully of my best friend

This story is about a girl named Tin Co who is 12 years old
She didn't know what her class was like, but I was quite active
She always tries to treat everyone around her well and tries to blend in with everyone so as not to be bullied.
And yes, she had a great time
She is close with two friends, one named L and one named N.
At that time, she felt like she would have a good time with her classmates.
Yet at the end of the year, she heard that her class would be separated and each child would be transferred to another class.
At that time, she was very scared, afraid of being away from her friends, afraid of not being able to make friends with anyone and being isolated.
Fortunately, she was able to study with N and some other friends in her old class.
Unfortunately, L is in another class
But it's okay, this new class is fun anyway.

Unfortunately, it wasn't as great as she thought it would be

What can I say, at that time she had some family problems

Do you think it won't be relevant?

If you think so, then you are wrong

At her house, every time she did something wrong, her relatives beat her to the point of having bruises all over her body. She was always cursed at. If she cried, she was beaten.

But when she told her parents, they also complained, but it seemed insignificant

Furthermore, she misunderstood that her parents said that because her brother only wanted the best for her and that it was just because he was worried.

And then gradually, that violence took shape in her thoughts

Every time N did something wrong or something made her feel wrong, she always tried to force N to follow her wishes

When N encountered difficulties, she did not help and even deliberately criticized N. And every time N cried, she did not comfort  but made N cry even more.

and then the negativity increased on Tin
Remembering the old days when her friends teased her, when she came home, she always heard her friends teasing each other. It was normal. Later, when she was bullied, she didn't know she was being bullied. but she misunderstood it as a joke.

With that distorted mindset, she accidentally became a bully without her knowing

she shouts and reveals or slanders and spreads fake rumors about N because she finds it funny and thinks it's a normal joke

She even ignored it when N's things were thrown away by her friends

She worked so hard that N couldn't stand it and took a day off

And when N was injured, if it were her in the past, she would be extremely worried and want to fuck the guy who injured N, but now she only pretends to care while feeling happy when N is like that.

For some reason, she didn't dare tell her parents about this, so Tin's group had even more motivation to bully her.

And then, after a certain event, Tin and Tin's brother reconciled

But Tin doesn't talk about things at school because she realizes she's become a bully

She tried many times to control herself and not bully N anymore, but she couldn't

and then came the vacation. Even though she didn't want to move, it was the only way she wouldn't harm N, and N's bullying would end.

And the last time we met, N didn't blame her and still considered her a friend
But she knew what she had become, so she treated N well one last time before moving away

Okay here's the story

I can't imagine any more

Sorry if there are any mistakes as English is not my native language
