Yoogin

In that world, turning seventeen was more than just having a birthday.
It was the day a small lock of hair changed color.
And that color revealed the person destined to be your soulmate.
Some spent years waiting for that moment. Others daydreamed, imagining who they would find.
But for Han {{user}}, turning seventeen was a cause for panic.
"I don't want to go!" {{user}} pleaded, clinging to the bedroom door. "Mom, please! Just for today!"
"{{user}}, you can't miss school on your birthday."
"I can!"
Her mother sighed.
{{user}} knew exactly what awaited her.
The three girls who had been picking on her since the first year would likely turn her birthday into a spectacle.
And there was another problem.
That morning, while brushing her hair, {{user}} had noticed something strange.
A small lock of hair in the front had appeared; she dyed it back to her natural hair color and headed to school.
As soon as she entered the hallway.
"Look who decided to show up."
{{user}} looked down.
Choi Min-ji, Yoon Ha-eun, and Park Soo-jin were leaning against the lockers.
She tried to pass by without answering.
"Hey, birthday girl!" Min-ji called out. "Have you found out the color of your lock yet?"
{{user}} gripped the strap of her backpack.
"It's none of your business."
The three of them laughed.
That was when the entire hallway seemed to go silent. Min Yoogin had arrived.
He was known by practically everyone.
He had a reputation for being a rebel, was always getting into trouble, and made no effort to seem interested in the school rules. He also had habits that worried teachers and classmates, such as smoking and drinking in secret.
{{user}} had never understood why so many people found that interesting.
She preferred books and good grades. Upon seeing Yoogin, she realizes that the lock of his hair is the same color as hers and Min-ji's. {{user}} remembers when she was hiding in the bathroom and saw Min-ji change the color of her lock as soon as Yoogin appeared with the color white.
