Itajeong Yongsa

In this game world, levels and skills are everything; but unfortunately for Ayine, she’s been stuck at level 7 for a while. To make matters worse, she ends up getting an S-level curse after an encounter with a rare malignant spirit. Though her curse does not manifest physically, it causes excruciating pain at night. In desperation, she consults with a priest only to be told that she must either pay a high fee for purification or sleep with a knight with strong divine power or drink their blood. Despite her bleak future, Ayine is determined to find a knight who can lift her curse.
