K [Jasper Liu] and Cream [Ivy Chen] first meet in high school, two orphans whose paths cross in a way that feels fated. K carries the weight of a stern past—his father’s death from cancer and a mother who abandons him—yet he also inherits a substantial sum of money, a quiet reminder of what life can hand you even when love seems fragile. Cream has known loss on a deeper level, having lost her entire family, and the two find in each other a rare sense of belonging. They decide to share a home and build something that resembles a family, a shelter from the storms that marked their youths. The bond between them grows into a deep, quiet soulmate connection that sustains them through their hardest days.
As time passes, K keeps a painful truth hidden: he has leukemia. He suppresses this truth to spare Cream, urging her to marry well and find stability with a kind and healthy man instead. His fear is not of illness itself but of becoming a burden to her, of letting her down when she deserves security and happiness. Cream, in turn, wrestles with her own longings and responsibilities. She voices an erotically loaded ideal of love and security, and she eventually declares that she has fallen for someone who appears affluent—a dentist who can offer a life of ease and safety. This revelation shatters K’s hopes in the moment, yet he finds a strange calm in believing that she has found her ideal partner, even if it is not with him.
Believing Cream has truly found love, K takes a difficult step to protect her happiness. He persuades Joo-hwan’s fiancée to break off that relationship, a move driven by a painful calculation: Cream’s future should not be tethered to a man who might fear illness or instability. She reacts in a way that reveals layers of complexity—one that later unfolds in her diary. The diary discloses that Cream learned about K’s illness not through direct conversation, but by rummaging through his belongings to seek inspiration for a song. What she discovers is not a dramatic confession, but the stark truth that the pills she finds are pain medication for terminal cancer patients. This discovery reframes her understanding of love, loyalty, and the limits of sheltering someone you care about.
Earlier in their shared life, Cream, aware of K’s illness, tests the boundaries of their bond. She asks him what defines a good man, and his answer—true generosity and steadfast care—becomes a yardstick that shapes her own decisions about love and life. This moment, revealed in her diary, underscores a tension between affection and practical protection, between tenderness and the ache of watching someone you love struggle with a terminal condition. The diary then becomes the vessel through which Cream’s thoughts—her fears, her doubts, and her evolving feelings—are exposed to the audience.
K’s health deteriorates, and the two spend their final day together celebrating Cream’s birthday. The mood is tender but tinged with the looming shadow of illness. When Cream asks what he wishes for, he answers with a soft, almost elusive line: “It’s a secret.” The moment carries an unspoken vow: if there is a next lifetime, surely they will find each other sooner. Cream teases him, half-joking, half-serious, that such a wish must have already been granted years before. Their last portrait as a family is taken in a moment of fragile happiness, a farewell frozen in time as K passes away.
In the aftermath, Cream makes amends with Joo-hwan, admitting that she wronged him. Joo-hwan visits the gravesite, and the visit carries a heavy implication: Cream may have taken her life after K’s death. The story closes on a note that honors their memory while leaving a sense of unresolved sorrow, a testament to the lengths two people will go to protect and preserve love, even when the cost is heartbreak and loss.
