The Vow of Never

I would rather fail my finals than fall for Park Si-woo.

In the hallways of Sehwa High, that was Kim Sia's golden rule. To the rest of the world, Park Si-woo is the golden boy-charming, brilliant, and effortlessly perfect. To Sia, he's a calculated menace who has spent three years turning her life into a competitive chessboard.

Their rivalry was legendary, built on stolen top-ranks, Sharpie-stained notebooks, and a mutual vow of eternal dislike. Sia was certain of two things: her ambition and her immunity to Si-woo's crooked smile.

But as graduation looms and the lines between academic warfare and genuine obsession begin to blur, (never) starts to feel like a very long time. From the frantic energy of high school corridors to a flower-strewn altar years later, this is the story of how a bitter feud became a lifelong promise.

Because on their wedding day, Si-woo only has one question: Remember when you said you'd never fall for me?
