Aria never meant to cross the line. When two powerful families strike a deal, she finds herself contractually engaged to a man she was never supposed to want, her best friend's past. It was supposed to be simple. Live in the same house, play the part, keep her distance. And most importantly, do not fall in love. Vivian made her promise. Aria meant to keep it. But distance becomes impossible when every glance lingers too long, when silence says more than words, and when the man she was never meant to have starts to feel like the only one who truly sees her. Now loyalty is no longer clear. Right and wrong blur into something far more dangerous. Because loving him means betraying her. And keeping her promise might mean losing him. In the end, Aria has to choose. But some choices do not come without consequences. And some betrayals cannot be undone.

The story of two academic rivals, their struggles and experiences throughout the chapters, how plots are involved and how romance developed over time.
