Lin Xiao and Su Chen met in college. One was a sensitive and independent photography girl who longed for stability but feared eternity because her father died young and her mother remarried. The other was a rational and pragmatic architecture boy who came from a poor background but made a vow to "stay together for the rest of his life." From the first time they met under the sycamore tree to the promise under the starry sky, they thought they had captured eternity. However, on the eve of graduation, Su Chen received an offer from a top firm in Beijing, but Lin Xiao had to stay in her hometown because her mother was seriously ill. Reality tore a gap, she took the initiative to break up, and the promise was shattered to pieces.
After the breakup, the two grew up separately: Lin Xiao became a well-known photographer, while Su Chen had a successful career but felt empty inside. Reunited five years later, they try to repair their old relationship and promise to reunite, but they hide secrets. As their relationship warmed up, Su Chen's secret was gradually exposed - it turned out that he broke up not just because of distance, but because he was diagnosed with a terminal illness and did not want to drag her down. The truth was revealed on the bedside, and the promise of "staying together for a lifetime" was finally completely shattered. Lin Xiao chose to let go and redeem herself, understanding that true eternity is not about being tied up, but about saying goodbye bravely.
