"Accidentally fell asleep on each other on the train"

What a long day. Her trainer really pushed her. The match was coming up in two days and if she was not prepared she was going to get her ass beat. Without even paying attention, Korra slumped down on a subway seat and made herself comfortable. She leaned her head against the uncomfortable and bumpy wall as the exhaust took over.

Her eyes fluttered awake as she felt a movement on her shoulder. More like, against her shoulder. ON THE WAY TO HER BREAST. Korra watched as his black hair moved from her collarbone to her boob. The next moment moved in slow-motion to her. She quickly stood up, startling her perverted intruder. Her hand moved on its own as it formed a fist which soon met his nose.

His hands flew to his face as he realized what was going on. She saw how his expression changed from pain, to surprised, to pissed.

"What the fuck is wrong with you?" the stranger screamed at her, "You broke my fucking nose!"

"You're the one copping a feel while I slept, pervert!" Korra yelled as she grabbed onto one of the handle bars above her, "Don't think I'd fucking notice?" She took note of the few phones that were now trained on her, and gave a death glare to the few who dared.

"I'm the fucking pervert?!" he stood up to match her stance, "You fell asleep on my shoulder, and it was comfty so I fell asleep, too. I'm so sorry my body moves on a fucking train when I'm alseep. You bitch." He was now using his shirt to soak up the blood.

Korra felt like an idiot. "Let me take you to the hospital," she offered as she grabbed her bag and his, "It's the least I could do. I'm so freakin' sorry."

Two hours later Korra sat in the hospital room with her victim. The man hadn't lent many words to her since they got there.

"I really am sorry. I thought you were trying to...well...touch my boobs." The man only grunted in response as he held the paper towels to his nose. The bleeding had stopped. Mostly.

"Does it...hurt still?" The man glared at her.

"Of course it hurts. You punched me in the nose." Korra cringed as he removed the paper towel from his nose. She could see how bad it was.

"I will pay for all of the bills, and I'll walk your dog, and do whatever you want." At that point the doctor finally came back in. They bandaged up his nose and spoke to Korra about payment options. Before they left the cleared him to go.

Korra walked the guy out, carrying his things. They both stopped when they got to the curb.

"Alright, you owe me a favor and I'm cashing it in. Saturday is this big work gala I have to bring a date to. My boss has required it. It's formal attire and I'll pick you up at 7. Please don't...smell like that." Korra was offended, but knowing how she treated him she bit her tongue.

"Can I know your name and number so I can text you my address?" Without speaking the man reached for his phone and had her put in her cell number. He grabbed his phone back, reached for his bag, and continued on his way.

Korra recieved a text that night. Be ready for our date on Saturday. Remember, 7. Send me your address. - Mako.
