Jiang Chiyan and Su Jinbai grew up together, and they were considered by others to be a perfect pair of academics. Five years after the separation, Jiang Chiyan returned to China in his sophomore year of high school. The two rekindled their bond on a familiar campus, and went from being tacit classmates to having a heart-to-heart connection. Even the parents of both parties calmly accepted the relationship.
They thought their happiness would last forever, until Su Jinbai kept complaining of stomach discomfort. At first, they thought it was a minor problem, but they were diagnosed with advanced gastric cancer just before their wedding. The moment the operating lights went out, all promises about the future came to an abrupt end.
Jiang Chiyan guarded the empty world alone. Every year on festival days, he took Su Jinbai's favorite chocolate cake to sit in front of the tombstone for a day, watching the aurora in Iceland for him, and finally ended his long longing for him at the place where his lover's name was engraved.
This is a letter sent to Iceland. The recipient will never open it, and the sender spent his entire life writing the ending.
Intention: Love is bounded by life and death, but longing transcends life and death. The unfinished agreement and deep love are written into a final letter sent to Iceland.
