Hi Bye, Mama! | Sogang University — The Campus They Used When the Hospital Needed a Past

People look for Jo Kang-hwa's student years on a generic Seoul quad. The Jesuit hill is this one. Sogang University occupies 35 Baekbeom-ro in Mapo-gu, on the slope above Sinchon. The campus opened in 1960. Red brick, the Albatross, and the short walk from Sogang University Station on the Gyeongui–Jungang Line still mark it. Korean Wikipedia lists the campus among the official Hi Bye, Mama! locations. The production needed a place that could carry medical-school memory without building a new set: courtyards, lecture-hall steps, the kind of path two friends would have used between class and a cheap meal. Kang-hwa and Gye Geun-sang's past sits more cleanly here than in a warehouse hospital. The grounds are publicly walkable during the day. Students still cut across the same brick. Stand at the main gate on Baekbeom-ro and the drama's flashbacks stop being a studio invention. They become a campus that was already here when the first broadcast went out on 22 February 2020.
