The right melody,that perfect voice when a high note is reached, the feelings involved, the passion and love. Music, his worlds necessary element. Donghae is a true talented singer, though he isn't quite sure he can call himself a singer since the only person he had sang to is his late father. No human being can replace a piece of his father not a little.

The day he decided to audition at SM that awful life- day when he was confident enough to sing to other than his father was the day he lost it all, his father his chance to succeed and his dream. Just three minutes before his turn, the news of Mr Lees death reached him, the shock, pain and anger blinded him. Donghae ran wildly home, the rain wasn't helping nor was the crowded streets. After a war with the rain he arrived,breathless looking around, there she was, his mother on her knees weeping, "Why did you go? Why?"
