This rooftop appears as Namil Bar where our friends always hang out in KBS2 Fight For My Way/Third-Rate My Way (쌈 마이웨이) (2017). It is also where Choi Ae-Ra’s (Kim Ji-Won) and Ko Dong-Man’s (Park Seo-Joon) romantic feelings start to show.
Namil Bar [남일바] is located in Busan’s neighborhood Beomcheong [Beomcheong-dong/범천동], in the Busanjin District [Busanjin-gu/부산진구]. It is supposed to be located on top of the Hansung Apartment Buildings [한성주택]. But both locations are about half an hour apart.
Apparently, still in 2019, the rooftop is still decorated in memory of Fight For My Way, when looking at this IG post from November 23, 2019:
