[Ending Warning: Full text BE, the heroine passed away due to illness and cannot be fulfilled, so please proceed with caution]
A chance encounter when I was a teenager quietly took root in my heart.
She and he were attracted to each other, and they knew the feelings hidden in each other's eyes, but they never broke through the window paper.
A sudden serious illness trapped her for the rest of her life.
She deliberately distanced herself, fearing a long separation and not wanting to drag down his future life.
When he mustered up the courage to confess, what awaited him was a farewell forever.
A belated frankness, a promise too late to be fulfilled.
Year after year, he was the only one left, guarding this secret love that had no beginning and no ending.
Concept: Encounter is precious, but regret is also the normal state of life.
