Bunshinsaba: Ouija Board

A small village school is where Yu-jin (Lee Se-eun) lands after moving from Seoul with her blind mother, and on her first day her classmates start in on her. Along with other girls the school has treated badly, she uses a Ouija board to curse the four who tormented them. Ahn Byeong-ki keeps the camera close and the pace slow, so the dread tightens inside the classroom before anything catches fire.
