Her only close friend, Seung-min, a doctor she has known since high school, reveals that Soo-yeon had tried to kill herself several times in the past.

Her college acquaintance and stalker also photographs her to build a shrine, and Detective Jo repeatedly gazes at her via surveillance camera.

The painting that scared Su-Yeon as a child and appears over the opening credits is a recreation of The Anatomy Lesson of Dr. Nicolaes Tulp by Rembrandt, which in turn references De humani corporis fabrica, recalling the anatomy theater of the Renaissance.

Kim writes that Tell Me Something directly engages the idea of scopophilia to purposefully draw attention to horror spectatorship and play with the voyeuristic nature of the viewer.
