Sierra Caroline De Luna, a simple girl living her simple life, but that was before the tragedy happened. She lost her memories and was drawn close to Zildjian Troy Villamor. He is a stranger, perhaps, just in her eyes, but he claimed to be her boyfriend. He, somehow, helped her regain her memories, but he made sure that she will never forget again, especially him. She was completely clueless of the past, but can she really trust him? Is he her knight wearing his shining armor or a coward hiding in his dark mask?
