Their names are not in the history books, but the iron box excavated at the Suzhou construction site in 2005 contained the most thrilling love story of 1937 - and the lives of three people.
On the night when Suzhou fell, medical student Su Qingyuan sneaked into the Kuomintang military camp to save his arrested father.
She hated the young officer Lu Zhengnian who ordered her father to be imprisoned, but when she was treating the wounded, she discovered that this man would modify the defense plan late at night to protect the people, risk letting the anti-Japanese students go, and run around all night just because she said, "The medicine is not enough."
When love sprouts in the smoke of gunpowder, the tragic death of his father tears everything apart. She fled to Shanghai with a blood oath, and he risked his life to deliver the iron box: "This is not a betrothal gift, but a contract - wait until I come back alive to marry you."
On the Wuhan battlefield in 1938, under the ruins, he handed over all the evidence: "Qingyuan, I have never betrayed you." When the gunfire rang out, they could finally embrace each other openly.
And the silent Adjutant Zhou guarded this secret all his life, until the cold winter of 1966, when he buried the manuscript on the eve of the criticism: "In the next life, I will still be the Adjutant Zhou who silently protected her."
In 2005, a rusty iron box was unearthed at a construction site in Suzhou, and a young researcher trembled as he read it - it turns out that what history has forgotten is the most thrilling truth.
In the torrent of troubled times, the words "love you" are too heavy and too far away.
