Quick Summary

In Seoul’s Buam-dong neighborhood, locals grew concerned when a cherished century-old ginkgo tree started withering in summer 2023. Residents formed a group of amateur detectives after noticing plastic funnels around the base of the tree, suspecting poisoning by a nearby museum dedicated to a Korean artist. The community sees the tree as a beloved symbol and “oldest friend,” leading them to rally together to save it from what they believe is an environmental threat.

Story summary

In Seoul, locals in Buam-dong noticed that one of their beloved ancient ginkgo trees was showing signs of severe distress this summer. Residents like Jung observed green leaves falling unusually early, forming a rotting carpet around the tree. Concerned, they formed an amateur detective team to uncover what was harming the hardy 100-year-old tree. The mystery gained national attention and sparked debates about environmental issues in urban areas. However, the heightened scrutiny also brought anxiety for Jung, who requested anonymity due to the pressure. She described the tree as a silent, ever-present grandfather figure that locals felt an emotional connection with.

Narrative

On the museum website, architect Woo Kyusung explains he wanted to create a space for Kim's works "that would complement the elements of the nature - the moon, mountains, clouds, rocks and trees - that were so important to his art". In fact, Kim wrote essays under the pen name Su-wha, which translates to "conversation with trees". The irony is not lost on Buam-dong's indignant residents.
