Obsession as Structural Engine
Building the whole plot on one character's fixation with a person, goal or rival. Every scene ties back to it, and the obsession keeps feeding itself while it destroys them.
How this film uses it
The murder investigation is the setup, but the film is really about Hae-jun's obsession with Seo-rae. Every step of the police work is a cover for the real story. He can't stop watching a woman whose guilt would destroy everything he is.
Where to see it
Hae-jun running surveillance on Seo-rae from across the street while she can see him. The detective and the suspect watch each other, so the watcher no longer holds the power.
