There was once a prince named Jonghyun, who lost his voice, and couldn't speak because of one jealous girl, named , who casted a spell on him for her unreturned love. Then one day, while he was just doing his usual rounds in the City Of Seoul, undercover, of course, he found a voice. A voice that was just so marvellous, he persisted to wait, on hearing her sing. And so, every night, he continued to come back, at the background of an alley, just to hear her sing. 

A month passed by, he continued to come, hearing her sing her voice out, and he was by then, found out. The girl's name was Luna, for she shined like the moon, in Jonghyun's eyes. She was shining more and more, the more she sang her heart out. He explained the reason for his presence-yes, he talked. He just couldn't sing beautifully any more as before. Luna, decided to help him, for her heart was like gold, she was kind-hearted and nice. 

Jonghyun started to fall on her, and he forgot almost every day, that he was once a prince, and that always almost forgot to go undercover, before seeing Luna. After a week of seeing her, Jonghyun's voice finally came back, slowly. Soon, he could already sing, but decided to hide it, for he wanted to be beside Luna more and more. She didn't even know, that Jonghyun was a prince, and that he had fall in love with her. 

Jonghyun finally confessed, surprising Luna with his miraculous voice, so miraculous that Luna accepted. The girl whos loved was unreturned, came back for him, now knowing that he could sing again. She did only her best, to make sure the couple broke up. 

Would Jonghyun and Luna make it til the end?
