The Anthem of the Heart

Jun lost her ability to speak after she accidentally exposed her father's infidelity, which led to family conflict. As a child, she imagined a fairy egg cursing her to seal her words so she wouldn't hurt anyone again. In reality, her muteness was psychologically self-imposed, she blamed herself for the family breakdown and developed a fear of speaking that manifested as physical stomachaches whenever she tried.

The film hints early on that Jun's curse is tied to her guilt and imagination, rather than being an external magical force.

The fairy egg was not a real creature, it was entirely a product of Jun's imagination. She created this imaginary being as a way to assign blame for her condition. When Jun realizes the egg was never real, she accepts that she was the one who silenced herself out of fear and guilt, not a magical curse.

The fairy egg only appears during moments of Jun's emotional distress, suggesting it originates from her mind rather than external reality.

Jun ran to the abandoned love hotel, the same location where she witnessed her father years earlier, because she was heartbroken after overhearing that Takumi still loved Natsuki. The location holds deep emotional significance for her trauma, and ironically, being in that space where her family broke apart allowed her to finally speak freely, as if confronting the source of her fear.

The love hotel is introduced in the opening scene as the place where Jun saw her father's infidelity, making it the symbolic source of her guilt.

Jun regains her voice gradually through singing, which bypasses the psychological barrier that blocks her speech. When Takumi explains that her muteness stems from fear rather than an actual curse, he encourages her to vent all her anger. This confrontation with her buried emotions releases her fear and allows her to speak normally again.

Jun's breakthrough occurs when she first hears Takumi singing in the committee room, showing that music can access what speech cannot.

No, Jun does not end up with Takumi. When she confesses her feelings to him, Takumi reveals he still loves Natsuki. Jun accepts this with maturity and thanks him for helping her find her voice. The film ends with Takumi and Natsuki reconciling, while Daiki confesses his feelings to Jun.

Early hints of the unresolved love triangle appear when Natsuki reveals she has a boyfriend who is actually Takumi, and when Takumi denies dating rumors from middle school.

Jun's curse was caused by her own guilt and fear. After accidentally exposing her father's affair and witnessing the resulting family conflict, she blamed herself for the turmoil. Her childmind created the fairy egg curse as a way to externalize this blame. The actual mechanism was psychological: the fear of hurting others with her words became so powerful that it physically prevented her from speaking.

The curse manifests whenever Jun tries to speak, causing her stomachaches, which connects emotional stress to physical symptoms.

The school musical becomes a vehicle for Jun to express her suppressed emotions indirectly. By telling her story through a fairy tale narrative, she can communicate her experiences without directly speaking. Performing the musical also forces her to confront her past publicly, and singing allows her to bypass her speech limitation, ultimately leading to her complete emotional breakthrough.

The musical is literally built from Jun's own life story, making it a therapeutic process disguised as a school project.

Takumi and Natsuki reconcile and get together by the film's end. Natsuki had liked Takumi since middle school and told classmates they weren't dating to protect herself from rejection. On the night before the musical, she finally admits to Takumi that she has a boyfriend, and that boyfriend is him. After Jun overhears this and runs away, Takumi and Natsuki eventually work through their misunderstandings and confirm their relationship.

The tension between Takumi and Natsuki is hinted at when Daiki asks Takumi about rumors of them dating in middle school, and Takumi denies them.

Jun intervenes in Daiki's conflict because she feels responsible for the group's cohesion and wants to help mend the rift. Even though her intervention triggers another stomachache, it strengthens the bonds among all committee members. This moment shows Jun moving beyond her passive role and actively participating in resolving problems, which is a crucial step in her character development.

The musical committee is specifically designed to bring these four students together, and this conflict tests whether they can work as a team.

At the end, Jun sings directly to her mother during the final scene of the musical, finally expressing all the emotions she has kept hidden. Her mother, Izumi, finally understands what Jun has endured, the guilt, the silence, and the pain. This moment becomes a healing point for their family, as Jun is able to communicate her true feelings through song and her mother receives them with understanding.

The musical is specifically about a daughter trying to deliver a message to her mother, making the final performance a literal fulfillment of that narrative.

Jun can speak at the abandoned love hotel because being at the location where her trauma began allows her to confront the root of her fear. When she finally expresses her anger and frustration openly, lashing out at Takumi, she breaks through the psychological barrier that had silenced her. Takumi's presence and his explanation that her curse was fear-based, not magical, gives her permission to release those emotions.

The love hotel was established as the site of Jun's original trauma when she saw her father leaving it.

Daiki develops romantic feelings for Jun throughout the story. After watching her work to help the group and seeing her kindness, he becomes drawn to her. At the end of the film, Daiki finally confesses his true feelings to Jun, bringing his subplot to a hopeful close, even though Jun does not reciprocate his feelings.

Daiki's interest is hinted when he asks Takumi about his relationship with Natsuki, showing he's paying attention to the romantic dynamics around him.
