A Century of Regret, Rewritten in One Book

The countdown to demolition in the old district has begun, and a 30-year-old bookstore is on the brink of closure. Its owner, Lu Li, makes an astonishing discovery: the pages tucked inside old books can connect to the time and space of their previous owners! Through yellowed letters and faded photographs, he becomes a “messenger through time,” traveling across a century to help countless strangers make peace with their regrets and resolve the knots in their hearts. But as the demolition crew closes in and the gulf between him and his mother weighs on him like a boulder, a “letter through time” from his mother’s youth suddenly appears. Only then does Lu Li realize that what he must save is not just the old street, but his own shattered family bond. Can he recover the love and memories he has lost amid the ruins, and protect the soul of the old neighborhood?
