Rumi's Betrayal and the Truth

The Manager's Mask: Rumi's Distorted Affection and Control

Hidaka Rumi appears in the film's opening as Mima's most reliable ally. Based on their shared background as former idols and a deep understanding of Mima, she shows a figure who constantly sympathises with and accommodates the difficulties Mima faces as she transitions to acting. In particular, the scene in which Rumi weeps and steps out when Mima has to perform the rape scene imprints on viewers the image of Rumi performing the role of a 'protector' who shares Mima's pain.

But Rumi's actions were never for Mima's sake from the start. All her consideration originated from a distorted possessiveness seeking to confine Mima within her sphere of control.

1. The Manifestation of the Desire to Control: The Construction of 'Mima's Room' and the Phantom

The decisive evidence that Rumi is deeply implicated in Mima's tragedy is revealed in the process of her feigning mental care for Mima. When Mima experiences the stalker's explosive incident, Rumi tries to smooth things over by advising her that it might be better to report it to the police. This shows that Rumi was trying to 'manage' the situation at the very moment when Mima needed to solve the problem herself and seek outside help.

Going further, when Mima experiences confusion between reality and fantasy, Rumi takes an attitude as if she knows everything. When Mima encounters the site 'Mima's Room,' Rumi dismisses it as simply an internet phenomenon and guides Mima to become immersed in that world herself. Even as Rumi witnesses people around Mima being murdered, she seems satisfied watching Mima crumble under external threats.

2. The Climax of Betrayal: The Emergence of the 'True Mima'

The point at which Rumi's betrayal explodes most dramatically is the film's finale. When Mima, completely mentally deteriorated, returns home with Rumi, she realises that the room she is in is the 'Mima's Room' that Rumi has staged. This room perfectly imitates Mima's past and present, but all of it was a stage Rumi had designed.

Harbouring resentment over Mima's retirement from the idol industry, Rumi had developed the persona of another self—the 'true Mima.' Unable to accept Mima's success as an actress, she seeks to destroy Mima and reclaim the image of the 'perfect Mima' she desires. In this process, Rumi pursues Mima and inflicts physical violence—skewering her side with the tip of an umbrella. This scene is not merely a chase—it is the completion of the psychological violence through which Rumi attempts to 'redefine' Mima's identity.

3. The Final Gaze: Between Control and Salvation

Rumi appears to save Mima from being hit by a truck, but this creates the paradoxical situation in which Mima saves Rumi through her own strength. The moment Mima screams at Rumi 'You're Rumi-san! Please come to your senses!!' Rumi retorts 'You're the one who needs to come to their senses.' This line shows that Rumi has completely lost herself between guilt toward Mima and the desire for control. Rumi is ultimately hospitalised, but the final scene—in which Mima looks at herself in the rearview mirror as she leaves the hospital and declares 'No—I'm the real one'—provides the denouement in which all the phantoms and control attempts Rumi manufactured are finally shattered by Mima's 'true self.'
