Summary
Sung Jin-Ah is the younger sister of Sung Jin-Woo. As the only sibling in their family, she shares a close bond with him while simultaneously maintaining a reputation as a diligent student who consistently achieves top marks on her exams. Her life has been defined by the traumatic events that befell her parents: her father became trapped within a Gate, and her mother fell into a coma caused by Eternal Sleep. Growing up with only Jin-Woo by her side, Jin-Ah lives in constant anxiety whenever he is hospitalized. This fear has led her to repeatedly urge her brother to quit his dangerous career as a hunter.
