Photo Retoucher A-nan returns to the old house that saddens him. The eerily beautiful yellow flowers on the loofah trellis attract a whole nest of ants. As a child, A-nan accidentally killed all these yellow flowers when spraying insecticide on them to kill the ants. In a rage, his father beat him lame. This caused a lifelong conflict between them. The elderly and paralyzed father, now wrapped in diapers and covered with ants, evokes the painful memories of A-nan’s youth. A-nan sprays and kills the ants again. But how will A-nan unravel this knotted relationship with his father, entangled for so many years? How will he restore the loving beauty of the yellow flowers that once bloomed in the courtyard?
