The children of our Buamdong Social Avengers Club — Lee Soo-Gyum (Jun of U-KISS), Kim Hee-Soo (Choi Kyu-Jin) and Baek Seo-Yeon (Kim Bo-Ra) — go to school here in Avengers Social Club (부암동 복수자들) (tvN, 2017); as we see for example in episode 1. It appears as ‘Sevit High School’.
Bong Pil (Kim Jae-Joong) and Kang Soo-Jin (Uee) went to this school when they where high school in Manhole (맨홀-이상한 나라의 필) (KBS2, 2017) and we see it often in flashbacks as for instance in episode 7 where Bong Pil fails (again) to confess his feelings.
Mush&Co go to school here in tvN The Liar and His Lover/Lovely Love Lie (그녀는 거짓말을 너무 사랑해) (2017).
This is also the school where Do Bong-soon (Park Bo-Young) and In Gook-Doo (Ji Soo) went to and where her gang of youngsters go to school in JTBC Strong Woman Do Bong soon (힘쎈여자 도봉순) (2017) as seen in episode 4 for example.
