奪命許願

구 홍성여자고등학교 충청남도 홍성군

The real school where the curse unfolds. The production used the closed former Hongseong Girls' High School, so most of the classroom scenes, from ordinary lessons turning bloody to Se-ah and her friends digging into the truth of the curse, were shot here. It is a separate campus from the currently operating Hongseong Girls' High School and has hosted other productions such as Moving. The site is not regularly open to the public, so plan to view it from the outside.

The Naepo New Town area doubles as the characters' route to school. Over roughly six months from March to August 2025 the crew shot 33 sessions around Hongseong, turning the new town's roads and streets into the drama's everyday neighborhood. As a planned city that houses the South Chungcheong Provincial Office, its wide, tidy streets let you walk straight into the show's commuting scenes.
