Lin Chan returns to the white house on the beach every summer to accompany Lu Mian, an oceanographic scholar who has been in a coma for seven years.
This is a secret contract between them - to meet only during the season when the cicadas are at their peak.
In the seventh summer, Lu Mian's attending physician informed Lin Chan that his physical condition was declining rapidly.
At the same time, his younger brother Lu Jue appeared with a dusty will, revealing the truth behind this sky-wide guarding.
When Lin Chan was sorting out Lu Mian's old things, he discovered a Haiyang diary.
The diary records the secrets of the year they first met: an unbleached coral sea and evidence of illegal sewage discharge by a certain group.
Lu Mian's coma was no accident - he chose to hide the evidence in her paintings and endure this long sleep alone.
Now that summer is approaching, the sound of cicadas is gradually fading, and the will is like a silent countdown.
Lin Chan stands at the intersection of truth and farewell.
She must make a choice: wake up Lu Mian and let the secrets from seven years ago be revealed;
Or continue to guard this aestivation and let everything dissipate with the summer.
