Since the moment of her birth, Evelyn could never see the color brown, a dull shade of grey stood in its place. It was the same color she saw while staring at herself in the mirror. She knew she'd continue to see grey until she met her destined half.

Following her daily routine of ordering a cup of hot chocolate at the cafè near her apartment, her world begins to infuse with brilliant shades of brown as she meets her destined mate-Kim Taehyung.
