Loyalty. Trust. Honor. Love. Magic. Taekwoon pledged himself to his kingdom, tying himself and his magic to it until the end of his days when he was just a child. But his loyalty has always belonged first and foremost to his heart...which has caused its fair share of grief over the years. Whilst chasing the desire of his heart, a merman siren named Wonsik, Taekwoon's life takes a sudden turn. A dragon prince falls from the sky and begs for help. Suddenly the war between love and loyalty becomes more complicated than ever before.
