Kim Seong-a

Kim Seong-a is one of the main character of White Day: A Labyrinth Named School. She was a student in Yeondu High School and was involved in a fire accident in 1998. During her high school years, she became a close friend to Han Na-yeong, whom she trusted very much and the trust was mutual between them. She is first seen by Hee-Min next to the Home Economics Classroom, talking to Ji-hyeon. Hee-Min's (your) sudden appearance gives her a scare, then she walks over to introduce herself. Her suspicions of Seong-a aren't obvious at first, but as you progress you'll soon find she tends to always suspect Hui-min for everything that's gone wrong. This is primarily because he is a newcomer to Yeondu High School, it seems as though everything started falling apart when he abruptly arrived.
