History student Shen Qingwan had just finished writing her thesis when she touched the old badge her grandfather had left her. The moment she opened her eyes, she had traveled back to the Republican era.
She didn't stay at the Shen residence as a wealthy young lady. Instead, she went out, found Chen Shouzhuo, and joined the base. To save the country, she sold her manuscripts, took on traitors, and even started playing matchmaker on the side.
Her schoolmate Lu Jingheng had also traveled back. To protect their identities, Shen Qingwan talked a mile a minute and pointed at Lu Jingheng, telling A Cheng, "That old geezer is my husband." She thought she was making it all up, not knowing that Lu Jingheng had long since begun looking at her differently.
Then it was confirmed that the badge and the pocket watch were a pair of tokens of love from a hundred years ago.
As it turned out, Shen Qingwan and Lu Jingheng of the Republican era were two heroic martyrs who had faced death side by side. Before setting out on their most dangerous mission, they entrusted their keepsakes to a comrade and promised that if they were ever reborn, they would meet again.
At the end of the story, the System's voice rang out: "Mission complete. You will be sent back to the modern era, and your memories will be erased."
Back in the modern era, Shen Qingwan woke with her head on her thesis and took it all for a dream. At their graduation dinner, the two ran into each other by chance, added each other on WeChat, and naturally fell in love and got married. Neither of them remembered their time in the Republican era.
Until, at their wedding, their grandfathers handed them the ancestral badge and pocket watch as tokens of love to exchange.
Even if I forget you a thousand times, even if a hundred years pass, I will find my way to you once more in this vast sea of people, and fall in love with you again.
