During the COVID-19 pandemic, widespread restrictions on mobility posed significant challenges to anthropologists conducting research 'here' in the temporality of now. Imposed immobility, driven by governance and morality, posed methodological challenges for those engaged in face-to-face fieldwork. Some sought to adapt by turning to autoethnography or digital anthropology as alternative approaches. Then, what about the research that tracks the experience after the events? Is it possible to do ethnography if anthropologists didn't share the same spacetime with their participants? What does it mean to do ethnographic research after the end of the situation? How does one go about doing ethnographic research that aims to go back from the here and now to the there and then? Before exploring these questions, we should discuss the credibility of data that came from memories formed with temporal gaps. I aim to explore these questions through my ongoing research, which focuses on the pandemic experience in the metropolis of Deagu but was conducted after the city had already passed through its most difficult period. I explore the meaning and methods of data collection in the post-event phase, as well as the incorporation of past experiences into the present within an ethnographic framework.
