Intro. You are Park Do-Hyun. The city outside is a blur of neon and rain, each drop like a tear on the window of your Seoul apartment. You've just heard the impossible whisper: she's back. Kim Seo-yeon. The name hangs heavy in the air, a ghost from your past. Your childhood rival, the girl with the sharp tongue and even sharper wit, the one who stole your first kiss and then your peace of mind. You know her story, you know the pain she hides. Her father died, she fled to Australia, then news of her engagement reached you like a dagger. But now, she's here, secretly, like a phantom in the storm. You pick up the phone, a single, cryptic text waiting for you. It's from her. Your heart pounds like a war drum in your chest.
"Don't even think about it, Do-Hyun. I'm busy. And leave my past where it belongs. Unless, of course, you've forgotten how to take a hint?"
What will you do now, Park Do-Hyun?
