15 Kapitel Laufend A marriage deal was meant to bind Kim Se-ra and Jeon Jungkook, the school's most untouchable and popular senior. But when Se-ra ran away with her boyfriend, all eyes turned to her younger sister-Kim Y/n. At just 17, shy and reserved Y/n never expected to be thrown into an engagement she never wanted, especially not with someone like Jungkook.
Jungkook, the bold, confident bad-boy-good-boy mix, had no interest in this arranged commitment-until he saw Y/n in the frame. A quiet girl, too innocent for the world, being forced into a decision she never made. And so, he agreed. Not for the deal, not for their families-but for her.
Now engaged in secret, Y/n and Jungkook must navigate their final year of high school while pretending nothing has changed. No one at school knows the truth. Jungkook is still the popular guy everyone desires, while Y/n fights to stay out of the spotlight. But when they're forced to live under the same roof, hidden glances turn into stolen moments, and arguments turn into something neither of them expected.
As feelings blur and secrets threaten to unravel, Y/n must ask herself-is she really just a replacement? Or was she meant to be his from the start?
💍 A secret engagement. A forced proximity. A love story neither of them asked for.
