Serim High School may be full of good-looking male students, but the school is actually an all-girls school called Shinmyung Girls’ High School in real life.
The school is located in Gangseok-dong, Namdong-gu, Incheon. Characters in “18 Again” including Go Woo Young / Hong Dae Young (Lee Do Hyun), Hong Si Ah (Roh Jeong Eui), Hong Si Woo (Ryeo Un), Seo Ji Ho (Golden Child’s Choi Bo Min), and Go Ja Sung (Hwang In Yeop) all attend the school as senior high school students. Jung Da Jung (student version is portrayed by Han So Eun) is an alumni of the school, alongside Hong Dae Young.
The fan favorite Korean drama “Reply 1988” also filmed in the school, this time as Sung Dok Seon’s (Hyeri) school. Other currently on-going dramas that are filming in this location include “The Penthouse” and “More Than Friends.”
