“Under Your Bed” (2023) is a tense psychological thriller that explores obsession, trauma, and the dangerous lengths people go to when driven by unresolved love. The story follows Ji-hoon, who cannot forget his college crush, Ye-eun. When he discovers that her marriage to the abusive Hyung-oh has drained her spirit, he becomes consumed with the idea of helping her—leading him down a dark and disturbing path.

The film builds its suspense around moral conflict rather than action. Ji-hoon’s choice to hide under the couple’s bed is unsettling, a decision that blurs the line between misguided protection and intrusive obsession. This uncomfortable tension is what gives the movie its gripping psychological edge. The narrative doesn’t romanticize his behavior; instead, it exposes the consequences of emotional fixation and desperation.

Ye-eun’s storyline adds emotional weight to the film. Her struggle within a violent marriage serves as the emotional core, highlighting themes of control, fear, and survival. The contrast between her vulnerability and Ji-hoon’s increasingly unstable behavior creates a chilling dynamic that keeps viewers on edge.

Visually, the movie uses tight, claustrophobic spaces and shadowed interiors to enhance its psychological intensity. The scenes beneath the bed—a space meant for safety yet turned into a prison of secrets—are some of the most haunting in the film.
