This is the portal that Kim Shin (Gong Yoo) uses in episode 7 of Goblin/Guardian: The Lonely and Great God (쓸쓸하고 찬란하神 – 도깨비) (tvN, 2016-17) to teleport Ji Eun-Tak (Kim Go-Eun) to school.
In episode 8, Eun-tak passes by this shop on her way to the bus stop Munhwa Park [문화공원] (and walks also by Shelley cake shop that is situated right next to JF Flower Shop).
JF Flower Shop is located in Anyang’s [안양시] neighborhood of Gwanyang [Gwanyang-dong/관양동] in the Dongan District [Dongan-gu/동안구].
Please note: Kim Shin also uses another portal in the same road in episode 8 — the door of shop Mina. It is five houses down the road.
