A young man reeling from a breakup is suddenly confronted by the literal ghost of lost love in Natsuki Takahashi’s supernaturally-inflected romantic drama A Girl in My Room (左様なら今晩は, Sayonara Konbanwa). Set in the peaceful town of Onomichi, the film finds its hero wasting away pining while wondering if falling in love with a ghost is all that bad only to later ask himself if any of it was real or just a fantasy of his lovelorn mind.
As the film opens, Yohei’s (Riku Hagiwara) girlfriend of two years, Rena (Riko Nagase), moves out of their apartment apparently sick of his superficiality and inconsiderate nature. Soon after, Yohei becomes aware that a ghost has been living in their apartment with them the whole time only should she couldn’t manifest because Rena apparently had unusually strong spiritual energy. Though originally frightened by the new presence, Yohei soon warms to the woman he names “Aisuke” (Shiori Kubo) and becomes determined to find out who she was and how she died only no one will tell him.
Of course, Aisuke could just be the symbolic ghost of Rena, a spectre of lost love confronting him with his romantic failure, but also seems to have an inner life of her own even if she can’t remember much about who she was when she was alive and how it was she came to die in the apartment. Fleeting memories seem to hint at a life of loneliness marked by romantic longing in which she wanted nothing more than a regular grown-up relationship though sadly it never happened for her. If she has unfinished business, then falling in love may be part of it but then it’s clear that any potential relationship between herself and Yohei is doomed to failure seeing as she is already dead.
Aisuke chose Yohei because she thought he was a good boyfriend after seeing him with Rena, but even so agrees that though he seems nice on the surface he never really thinks about anything and responds to criticism by smoothing it over with an apology rather than reflecting on his actions or trying to better himself. Work colleague Kanan (Rina Ono), who also has a crush on him, conversely claims that Yohei shows his kindness too easily though also remarking that kindness in itself can also be problematic. In any case, as he bonds with Aisuke, Yohei does seem to engage more with his flaws and reflect on the mistakes he may have made in his relationship with Rena in order to become not just a better boyfriend but a better person.
In these respects, Aisuke becomes a romantic mirror confronting him with the problematic aspects of his own personality but somehow gaining in corporeality as the relationship progresses as if love were bringing her back to life. But then Kanan also claims that that’s because Aisuke is unwittingly sucking the life out of him which is why he looks tired and gaunt. A picture she took of him on her phone has a dark aura over his face hinting at something malevolent at work that’s taking a toll on his health. But as much as he’s warned, Yohei determines to stay with Aisuke, slowly falling in love with her in the wake of his failed relationship.
Partly a fable about the dangers of remaining trapped by the ghost of lost love rather than resolving to move on, the film is also a poignant love story in which the pair must help each other overcome their mutual unfinished business while becoming aware that their liminal romance cannot continue forever. A side plot involving an estate agent and his endless calls from a confused older gentleman randomly asking him for legal and life advice hints at other kinds of living ghosts and urban loneliness but also at those willing to take care of them as perhaps the estate agent did with Yohei and Aisuke in a bit of supernatural matchmaking helping each of them to begin moving on with their lives on either side of the mortal divide. Charmingly quirky and comforting in its tranquil setting, Takahashi ends on a poignant, bittersweet note but also one of warmth in which the ghost of lost love doesn’t so much haunt as abide, a constant source of comfort in a lonely existence.
