Lee Heeseung was a man who seemed to melt into the shadows. His past was a locked box and his present a carefully constructed facade. Kang Minjun was an artist, her canvases bursting with vibrant sunflowers that defied the gray concrete around them. She was sunlight personified, a stark contrast to the darkness Heeseung embraced. From the moment he laid eyes on her, a fierce, possessive yearning took root. He watched her from afar. His desire was a hunger that couldn't be sated with mere gestures. He wanted her attention, her trust and her everything. She sensed the watchful eyes, the unseen presence. She saw a flicker of something intense, almost desperate in the shadows whenever she glanced too quickly. Who was this man, and why was he so obsessed with her? And more importantly, what would he do to possess the woman he believed was his temptation?
