Years go by, K works for a record company and Cream becomes a lyricist, but they still live together, neither a couple nor friends. When K is diagnosed with leukemia, he is hesitant to reveal his illness to Cream because he does not want to hurt her by leaving her alone. He also struggles with the idea of confessing his love for her. Unaware of this, Cream starts dating another man, eventually accepting his marriage proposal.
