Cream, played by Lee Bo-young, is a gifted musician who lost her entire family and becomes closely connected to Kay's world. Her relationship with Kay is defined by mutual, unspoken devotion, she knows about his illness while he believes he's hiding it from her. She tests their bond by feigning romantic interest in another man (Joo-hwan) to ease Kay's burden and allow him to die peacefully. Her diary reveals the emotional cost of caring for someone terminally ill while maintaining the pretense of ignorance.

Kay's leukemia is the invisible engine driving every crucial choice in the film. Rather than focusing on medical details, the film portrays how a terminal diagnosis fundamentally alters one's perception of time and priorities. Kay chooses to prioritize Cream's future over his own, creating painful but deliberate distance. The couple's celebration of Cream's birthday becomes a poignant metaphor for capturing final vivid memories, while mortality casts a constant shadow over their interactions, giving even mundane moments profound emotional weight.

The film presents love as an act of protection that sometimes requires painful deception. Kay's love manifests as withholding the truth, he wants Cream to live without the weight of watching him die. Cream's love involves playing along with his deception while quietly bearing the emotional burden. The narrative suggests that true love sometimes means prioritizing the other's happiness over being together, even if that means accepting being pushed away. Their bond is defined by secrecy, devotion, and a quiet hope to be together beyond pain in some form.

Deception serves as both the film's central mechanism and its moral complexity. Kay deceives Cream about his illness to shield her from pain and push her toward a healthier life. Cream deceives Kay by pretending not to know his secret, while simultaneously manipulating situations using Joo-hwan as part of her plan. This creates a paradox where both characters are lying to protect each other, raising questions about whether honesty is always the highest form of love. The narrative explores the ethical tensions of caring through deception and whether benevolent lies can be justified in intimate relationships.

The film maintains a predominantly melancholic and heavy emotional tone throughout, driven by themes of terminal illness and secret sacrifices. Despite some tender moments between Kay and Cream, the underlying sadness is ever-present. The SadnessScore is rated very high (9) due to the dual tragedies of Kay's death and Cream's implied suicide. The RomanceScore is equally high (9) as the entire plot revolves around their profound, unfulfilled romantic connection. The tone is steady and character-driven rather than action-oriented, deriving its power from the quiet, internal tragedy unfolding between the two leads.

The film explores afterlife and memory through the couple's final photographs together and the lingering impact of their deaths. After Kay dies, Cream's implied suicide leaves a haunting imprint that extends beyond the screen. However, the dialogue hints at a belief in a next lifetime, suggesting that their love might continue beyond death. This provides fragile hope amid overwhelming grief, inviting viewers to reflect on how love persists through memory and imagined reunions. The theme suggests that bonds formed through such profound sacrifice may transcend physical death.

The title More Than Blue likely references the pervasive sadness (blue) that defines the film's emotional landscape, suggesting the story is about emotions deeper than ordinary sadness. The film's Korean title and its tagline 'A Story Sadder Than Sadness' reinforce this interpretation. Blue as a color commonly represents melancholy, and the title implies that the characters' experiences, and their love, transcend typical sorrow. Their relationship involves complex layers of sacrifice, deception, and unspoken devotion that create a depth of emotion more profound than simple sadness can capture.
