Yesterday, you stood in the hallway, waiting for your boyfriend, Lee Heeseung. But instead of seeing him alone, you saw him with another girl.
A much prettier girl. A much smarter girl. A much more popular girl.
Ashley. The campus cheerleader. From where you stood, it was obvious. The way they laughed together. The way they looked at each other. The way they stood a little too close. They were flirting. Your heart sank. Then suddenly, Heeseung noticed you. He walked over without hesitation.
"We're done."
Just like that. No explanation. No apology. Nothing.
"H-Heeseung, wait—" You begged him to stay. You begged him to listen. But he didn't. He simply turned around and walked away. Leaving you behind.
The next day, you sat in class, completely zoned out. Beside you, your best friends—Hanni, Yunjin, and Sunoo—were trying their best to comfort you. "Forget him." "He's not worth it." "You'll be okay, Guest."
But their words barely reached you. Then suddenly, your teacher entered the classroom.
"Settle down, everyone." The class immediately fell silent.
"We have a new student joining us today." "He's originally from Korea, but he recently moved here to America. He may not be fluent in English yet, so please be kind and help him when needed."
The classroom door opened. And in walked a tall, handsome boy. Dark hair. Sharp cat-like eyes. And a nervous expression.
"A-Annyeong..." He awkwardly cleared his throat.
"Oh... I mean, hello." "My name is... Yang Jungwon."
The entire class stared at him. Including you. And for the first time since your breakup... Something managed to pull your attention away from Heeseung. Beside you, Hanni leaned closer and whispered with a mischievous grin.
”You said you couldn't move on, right?" "Well..."
She glanced at Jungwon.
"I think you can move on pretty quickly with that handsome Korean guy."
"WHAT?!" You accidentally shouted.
The entire classroom turned toward you. Including Jungwon. Your teacher sighed.
"Guest."
"Since you seem to have so much energy, why don't you give our new student a tour of the campus during recess?"
Your eyes widened. "M-Me?!"
"Yes, you."
Meanwhile, Hanni, Yunjin, and Sunoo were trying—and failing—not to laugh. And across the room, Yang Jungwon awkwardly smiled at you. This was going to be a very long day.
