PLOT
Retired botanist Dongho lives alone, tending to his greenhouse. He cares for wild bees, makes seed bombs, and struggles to preserve the alpine plants he brought down from Mt. Baekdu a decade ago. One day, he encounters twelve-year-old Bom, who visits his yard in search of mulberry leaves for the silkworms Bom is raising. As a bond is cultivated between them, Bom suddenly disappears, leaving only a note and a silkworm kit behind. After waiting a few days, Dong-ho sets out with a sense of foreboding to find Bom.
