In the summer of seventeen years old, introverted Lin Chen wrote his first confession letter in his life, but he never had the courage to send it to the girl who made his heart beat - Lin Xinran. This letter was quietly hidden deep in the drawer for ten years.
Ten years later, Lin Chen, who was already a company executive, accidentally discovered this dusty letter when he was sorting out his old belongings. On the yellowed letter paper, the childish handwriting is still clear, carrying the memory of that young and pure love. At this moment, an invitation to a high school reunion rekindled his hope.
The reunion at the party revealed a heartbreaking truth: It turned out that Lin Xinran also loved Lin Chen deeply back then. She had been waiting for his confession, but she also chose to remain silent because of timidity. Two people in love missed each other for ten years because of mutual misunderstanding and hesitation.
This is a love story about waiting and courage, regret and reunion. When the dusty secrets are revealed, when the belated confession is finally spoken, can they start over? Can the letter that was left unopened at the age of seventeen finally find its destination?
