I Won't Break My Promise. (RWBY)

"Tired of Running Away"

Nora watched Yang run at Sun at full speed, wondering if she should jump in too or just let Yang do her thing.
Sun had a look of surprise but didn't move, seeming to be frozen in place by how quick she was and how little time he had to react.

Nora was leaning on the side of letting Sun get his ass kicked by Yang and watching with some popcorn.

He kinda deserved it...

No, he does deserve it. How dare he?

As soon as Sun started disrespecting Yang and got exposed for cheating on Blake, Ren immediately grabbed Nora in a bear hug, restraining her.

She was trying to hold in the urge to punch him in his face, but his comments to Yang did nothing but set her off.

At the moment Nora is currently struggling to get out of Ren's grasp.
"LET ME BREAK HIS LEGS!"

Jaune was on his way to get Yang, but she was faster.

If you blinked, you would've missed her.
It was almost as if it were in slow motion.

Yang cocked her arm back and punched Sun in the face with her left hand, luckily she didn't use her mechanical one otherwise he'd probably get a concussion.

Blake, aware of Yang getting ready to punch him again, ran over to her.

Before she got there, Sun pushed Yang away from him, trying to avoid another hit. "I am not above hitting a girl who is trying to attack me."

Jaune gave him a look of digust. "So you were planning on beating up a female?"

"Let's be real here. Yang has the strength of 10 grown men. Am I not allowed to freakin' defend myself?"

Neptune chimed in. "Uh, equal rights?"

"Shut up, Neptune." Nora said, angrily.

"She hit me first!"

"-and Im ABOUT to hit you again."

Blake took Yang's hand.
"No you aren't. Stop."

Yang glared at Sun. "But he-!"

Blake looked the blonde in her crimson eyes.
"Don't look at him, look at me."

"Let go of me, Blake."

"If you hit me I will hit you back, Yang. Sun said, rubbing his bruised face.

"You wanna fight? Let's fight then. I had about enough of you."

Yang snatched away from Blake's grip and leaped into action, throwing furious punches at him.

Sun took a couple steps back attempting to dodge the brawler's attacks.

Yang quickly closed the distance between them, as Sun threw an open hand at her catching her fist into his.

She snatched her fist back.
"Hit me, I dare you."

Blake watched in horror hoping they wont seriously hurt each other.
"STOP!"

Noticing Yang was distracted by Blake, he backpedaled farther and reached for his staff.

They all had their weapons around, you never know when a Grimm attacks or when an enemy is lurking. Although they didnt think they'd be using it on each other.

He had no choice, he needed it to protect himself, atleast that's what he thought. He was against a strong drunken opponent.

Sun having liquid courage is probably the reason he had the balls to fight back.
