More Than Blue

K and Cream, both orphans, meet during their high school years. K reveals that his father died of cancer but left him a sizeable sum, while Cream has lost her entire family. They become soulmates and decide to share a home.

K keeps his leukemia a secret from Cream and worries about being left alone. He urges her to marry a kind, healthy man so she won't suffer after he's gone. This sets the tone for their complex relationship and the sacrifices he makes.

Cream announces that she loves an affluent dentist. K feels heartbroken, yet he accepts that she has found her ideal partner. He tries to support her happiness while concealing his own pain.

K is heartbroken by Cream's choice, but he is relieved that she has found someone who can provide stability. He continues to act as her ally, masking his illness and fear behind a calm exterior.

K approaches Joo-hwan's fiancée and asks her to end the engagement. She agrees only if K lets her photograph him for a death-themed exhibit, revealing his willingness to cooperate for Cream's sake and to face death openly.

Cream rummages through K's belongings to find inspiration for a song and unexpectedly discovers medication associated with terminal cancer care. This revelation confirms the seriousness of K's illness and reshapes Cream's understanding of their relationship.

Earlier in their relationship, Cream asks what defines a good man, and K responds that a good man is someone who is healthy and able to protect those he loves. This exchange is later revealed in Cream's diary, underscoring her calculated test of him.

With knowledge of K's illness, Cream pretends to fall in love with Joo-hwan to comfort and appease him, masking her true feelings and the strategic nature of her actions.

K's condition takes a drastic turn and Cream spends their last day celebrating her birthday with him. When asked what he wishes for, he keeps it a secret, hinting at a future reunion in another life. They share a final, meaningful moment together.

As they take their last picture as a 'family,' K's health worsens and he passes away shortly after. Cream and their makeshift family are left to confront the loss and the emptiness that follows.

Cream apologizes to Joo-hwan for cheating him, and Joo-hwan visits their grave, indicating the depth of the tragedy and suggesting Cream may have taken her own life after K's death.

The story closes with implications of Cream's suicide and the unresolved toll of living with loss. The final moments emphasize grief, memory, and the costs of hidden truths.
