Addiction - Manhwa

The abandoned princess wished to bring down the imperial family. So, on a cold winter night, Estelle awakened the blue-eyed devil who had been slumbering in the Ice Castle. "Make me the emperor." The beautiful devil, surrounded by pure white snow, ice, and a rich floral fragrance, accepted the contract and whispered. "Welcome to hell, Estelle." Estelle thought that night was her first encounter with the devil, but there was an old, forgotten first contract between them... "The year you come of age. On the night of the full moon in midwinter. The day the doors of the Ice Castle open. Promise to summon me then."
