Love Untangled

Se-ri realizes she never truly loved Hyun after spending time with Yun-seok. During the school trip, she understands that genuine love comes from being accepted as she is, not from changing herself. Yun-seok had consistently supported her without pretense, making her feel beautiful with her natural curls, which contrasted with Hyun whom she only pursued as an idealized version of herself.

Earlier scenes show Yun-seok secretly caring for Se-ri while she remains focused on her superficial goal of straight hair for Hyun.

Yun-seok sabotages the straightening because he loves Se-ri exactly as she is, curly hair and all. He cannot bear to watch her change herself for someone else when he accepts her fully. By washing her hair with conditioner, he ensures the straightening fails, hoping she'll see that her natural self is worthy of love.

Yun-seok's earlier compliments about Se-ri's curls and lively spirit hint at his deep affection for who she truly is.

Se-ri ends their relationship via voicemail because she believes it's the only way to free Yun-seok from being trapped in a life without him. Knowing his father is forcing him to move to the US and that staying would mean a difficult life for both of them in Korea, she sacrifices her own happiness by pretending she no longer loves him, allowing him to leave without guilt.

This decision mirrors Se-ri's earlier character arc of learning to put others' needs before her own superficial desires.

The jar of folded paper pyramids represents every moment Yun-seok thought of Se-ri during their months apart. Each pyramid is a tangible memory of their time together, symbolizing his constant love and mental connection despite the physical separation. It demonstrates that his feelings never diminished even while they were apart.

The paper pyramids connect to earlier scenes where Yun-seok folded paper during moments of emotional stress, establishing this as his coping mechanism.

Yun-seok returns because he never truly left, she was his reason to live ever since she saved him from drowning. Despite moving to the US, he comes back because their love was stronger than the circumstances that separated them. His return represents his choice to prioritize their relationship over his father's control.

Yun-seok's earlier confession that saving him gave him a reason to live establishes his deep emotional dependence on Se-ri.

Se-ri studying marine sports with her natural curls represents her complete journey of self-acceptance. She no longer needs to change herself to be loved, her natural appearance is now part of her identity. This contrasts sharply with her earlier obsession with straightening her hair, showing genuine personal growth.

The entire movie's conflict stemmed from Se-ri's insecurity about her frizzy hair, making this transformation the culmination of her character arc.

The film leaves the specific outcome ambiguous but implies Yun-seok escaped his father's control by returning to Korea. His mother being hospitalized initially seemed to trap him further, but his ability to return suggests he found a way to break free from the abusive household, likely with his mother's support or independence.

Earlier hints of Yun-seok's difficult home life and his father's pressure about the CSAT establish the severity of his situation.

Se-ri's confession marks the turning point where she stops pursuing an idealized version of love and embraces real emotional connection. By telling Hyun her feelings have shifted and then admitting her love for Yun-seok, she completes her transformation from a girl seeking external validation to someone who understands genuine affection comes from acceptance.

The buildup to the school trip proposal had shown Se-ri's hesitation and growing awareness that her feelings were changing.

Yes, the ending is a definitively happy reunion. After months of painful separation caused by Se-ri's voicemail sacrifice, Yun-seok returns with the paper pyramids and proposes reuniting. Se-ri's tearful nod confirms they get back together. The final embrace resolves their story with hope, though the film acknowledges they overcame significant obstacles to reach this point.

The hopeful tone throughout the film, despite darker moments of abuse and separation, sets up this positive resolution.
