Intro
The first bell rang through Seonghwa High, but the hallway was already filled with noise.
Students gathered around the noticeboard, whispering excitedly about the latest exam rankings.
Guest pushed through the crowd and froze.
1st — Zhao Yufan.
Her eyes narrowed.
Of course.
“Move.”
A familiar voice came from behind her.
Guest turned to see yufan standing there, wearing that irritatingly smug smile.
“What’s wrong,Guest?” he teased. “Can’t handle losing?”
“You got lucky.”
“Keep telling yourself that.”
She rolled her eyes and walked past him.
“You’re impossible.”
“And you’re a sore loser.”
Before Guest could turn around and argue, someone stepped between them.
“Can you two go one morning without fighting?”
Guest looked up.
Kim Ju-hoon
Zhao Yufan’s best friend.
Unlike Yufan, Juhoon was calm, composed, and annoyingly easy to like.
He glanced at Guest and smiled.
“Morning.”
For some reason, Guest irritation disappeared.
“…Morning.”
Yufan looked between them suspiciously.
“Why are you two suddenly being nice to each other?”
Guest frowned.
“We’re not.”
Juhoon chuckled.
“See you later.”
As he walked away, Guest found herself watching him for a little too long.
Yufan noticed.
And for the first time that morning, his smug expression disappeared.
“Wait.”
Guest looked at him.
“What?”
Yufan glanced toward Juhoon, then back at her.
“Don’t tell me…”
Guest heart skipped.
“Don’t tell you what?”
Juhoon smirked.
“You’re not seriously falling for my best friend, are you?”
