Question - step mother looking down (spoilers!)
At the beginning of the films, when both sisters step into the house, and (allegedly) Sun-Ju aproaches them and talks, at some point she stares at something bellow Su-Yon, with a bewildered expression and tries to reach for it, but the girls back away.
What do you think that was? It cofunsed me a bit, though I did ponder that maybe it symbolizes Su-Yon being under ground (being dead), or the hanging of the biological mother.
