My Sweet Heart Vol. 1 (novel‪)‬

A one-night stand. A runaway Cinderella. A prince left waiting.

Isabel Lance was a phantom. As the illegitimate daughter of Baron Lance, she was viewed as undeserving of any attention, a ghostly figure that blended into the wall at social gatherings. Isabel was comfortable with her position as a wallflower, for it allowed her the chance to gaze endlessly at the man who held everyone's attention—Agares Halen Arthas, the Grand Duke of Arthas.

Upon discovering her beloved Agares stumbling into a room, she seizes the opportunity to take a closer look. But after their encounter turns passionate, Isabel flees the scene. Unexpectedly, the grand duke, who's arguably the most famous man in society, is now on the hunt for her.

Agares is persistent in his search for his runaway Cinderella, and Isabel can't resist the temptation of letting herself be caught. Thus begins a bewitching entanglement of hearts and desires. Can a woman who has never known affection teach a man admired by all the meaning of true love?

Sometimes, it takes a serendipitous encounter to uncover the sweetest of hearts.
