While Lovely Horribly started with a unique premise blending horror and rom-com, it struggled significantly with viewership.

The series debuted with modest ratings (around 4.8% to 5.0%) and peaked at 6.2% during its 10th episode. However, ratings steadily declined as the show went on. It infamously hit a record low of 1.0% nationwide during the Chuseok holiday broadcasts, making it one of the lowest-rated primetime dramas ever to air on a free-to-air public television network in South Korea.
