At Jiang Jinghe's engagement party, she seemed to see Gu Huailin, who had been missing for three years, completely losing control of her dusty love and grievances. After being hospitalized with a high fever, she fell into an extremely realistic dream: she and Gu Huailin abandoned their family ties and ran away to Dali, owning a small building and studio facing the Erhai Lake, making a marriage contract that belonged to them, and imagining a stable and stable life together.
When he regained consciousness, all the dreams were shattered by reality: Gu Huailin died in Dali three years ago. Her family members were afraid that she would collapse, so they worked together to hide the news of her death, allowing her to live in the lie that "he had gone away" for a long time.
Those days and nights together and the Erhai Lake were all illusions spawned by trauma, illusions woven by the unfinished obsessions in her heart. Gu Huailin left a suicide note before his death, admitting that saying goodbye without saying goodbye was a cowardly escape, and that she should not have chosen her life alone. But the belated truth was too heavy, and Jiang Jinghe could not reconcile with the incomplete reality, and finally followed his lover in the midsummer. All regrets left were lingering echoes in the summer.
