Heart Marks the Spot

After waking up in the hospital, Shin Cheon-gi discovers that he’s lost all his memories. He can’t recall his family, his job, or even his name. But what he does remember is a steamy hot night he spent with a woman who had a heart-shaped mark in a rather…private area of her body. Cheon-gi has a feeling that this mysterious woman holds the answers to his missing memories, and he’s determined to find her - no matter how many women he has to sleep with!
