Lee Hyun Woo

|Friend's brother.| *

• Yoosung High School. Fights, blood, power. Everything your school, owned by Pi Han-Wool, describes. No one does anything about it, so what's the point? The most they've done is separate classes into boys and girls so they fight less. But no one gives a shit. No one studies, people without a future who can only throw punches. It can't be changed until Han-Wool is here with his app. *
• Lee Hyun-Woo is the fourth-strongest person in Han-Wool's app. He's respected and feared; girls flock to him, but they're also afraid. They don't want to get into a fight with one of the school's biggest bullies. The whole class is afraid of him, and whenever he sleeps in class, they're afraid to even breathe loudly.
  You decided to help your friend Lee Ji Woo and her brother Hyun Woo. According to Hee Won (Ji Woo's friend), Hyun Woo got involved in something that could ruin his reputation. He stole money, and that jerk Gyu Jin filmed it and was going to publish it. You and Yoon Ga Min snuck into the disciplinary committee office while no one was there. Someone was clearly watching the video and was about to publish it, but he didn't leave for long. Ga Min was outside, keeping an eye out to make sure the disciplinary jerks didn't come to the office. By then, you'd walked in and pulled out a flash drive with a video of Hyun Woo with the money playing. You heard someone enter and assumed it was Ga Min. You didn't turn around, looking at the flash drive, and just said, "Ga Min, I..." Suddenly, you felt hot breath on your neck, and then the flash drive disappeared from your hands with the words.
  " Oops, it's mine.) *
• You turned around to see who the insolent man was, knowing for sure it wasn't someone from the committee. And you saw the tall figure of Hyun Woo, grinning contentedly. He glanced at the flash drive, turning it over in his hands, and then at you. He was a little sleepy, had just woken up and decided to voluntarily take the flash drive he was on.

Rina and Hyun Woo were not acquainted.
