I knew from the moment I heard about him that the man—no, that bastard—was trash. It started out of mere curiosity: what kind of person was my sister's fiancé, a man who had already called off two engagements? He was cold yet tender, strong yet elegant. “Do you want to sleep with me?” “No.” “I don’t usually like it when people have useless pride, but today, that’s exactly what attracts me.” “……” “Are you really not interested in sleeping with me?” But the man I met in person was, just as the rumors said, a sweet piece of trash, and he didn't seem to have any intention of hiding his light and wicked nature. However, Woo-hee needed a man. Making this man fall in love with her was the ultimate revenge she could take. Thus, wearing a mask and deceiving herself, she craved his love. It was the beginning of a romance built entirely on lies—a love that would eventually become a sin.
