Book Title: the Love Letter Has Faded

Twelve years is enough time for a youth to rot into regret, and enough time for an unsent love letter to slowly develop in time. Lin Jianwei's thoughts that he had hidden for half his life were all reflected in the unsent words - his secret love for Zhou Shubai, his longing for Su Nian, and his perfunctory treatment of himself. She is an editor who records other people's stories, but she locks her deep feelings into the pages and never dares to speak them out. Zhou Shubai has measured countless buildings with architectural drawings in hand, but failed to see clearly the emotions in his eyes when he was young. He always thought that important words could be saved for the future, until "the future" became an unreachable past. From being side by side on the university campus at the age of eighteen, to their respective ups and downs in the city at the age of twenty-five, to their sudden reunion on the street corner at the age of thirty, they have gone through three periods of time and experienced countless bifurcations. Su Nian's enthusiasm and exit, Chen Yu's compromise and separation, Gu Nanyin's appearance and farewell, all tell the emotional truth of adults: friendship will fade quietly over the years, love is often trapped in the lag of expression, and life is about learning to reconcile with oneself through regret. Those unspoken confessions, silent farewells, and thoughts that have been delayed by time, resurface at the moment of reunion. This time, can they break the shackles of "I didn't tell, you didn't ask" and catch each other's affection that was twelve years late? This is a group portrait that has grown up over more than ten years, hiding the dislocation and regret that everyone has experienced, and finally leading to gentle look back and reconciliation.
