Lin Yu loved Su Wan for 3000 days.
From the startling glance in the midsummer of the first year of high school, to the silent watch in the same university city, everyone knew about this secret love, but he was the only one who dared not announce it to his mouth.
She knew it, but always kept her distance, and later embraced others.
He didn't complain or bother, he just wrote all his worries into unsent letters and locked them in an old box.
When she received a call for help before graduation, he rushed over to protect her and stayed in the 22-year-old summer forever.
When 3,000 love letters were made public, the tenderness, humility, obsession and deep affection that had been hidden for seven years were revealed in tears.
Su Wancai suddenly realized:
That extremely silent boy spent his whole life falling in love with her.
And she was left with endless regret.
Secret love turns into sorrow, separated by life and death. This is a love that no one knows, but it is difficult to let go of a lifetime.
