Born from the same mother, Serena and Serenia are twin sisters born from the Night Goddess, the goddess who watches over the night and the darkest parts of the world. The two sisters look alike, yet in many ways, they are completely different. Serena, the eldest, took after her mother. She inherited her gentle nature, her powers, and her duty.

Although the two sisters are different and are constantly compared to one another, they have always shared a good relationship. But what will happen when a mysterious heir arrives? Which sister will he choose? And what will happen when the two sisters find themselves falling for the same person?
