Synopsis:
As an 18-year-old student at a magical boarding school, "I" made a fateful decision: to trade my heart to a witch in an occult ritual.
The witch's ritual granted all my desires – adoring crowds, unprecedented status, and a grand romance. But the crowds turned faceless, power became a viper's nest, and love... How could I possibly respond to his affection... when I had no heart left to feel?
