Shen Huiqi, a high school transfer student, is lonely and taciturn, with a dark childhood behind him.
Until that day, he met his deskmate Shi Qing, who was quiet, stubborn, but gradually losing his memory.
Those hands with the same old scars, the vague words "I protect you", the same sweet smell of roasted sweet potatoes...
Everything is repeatedly tapping into his dusty memory.
He recognized her instantly.
But in her illness and forgetfulness, she could never remember the light that illuminated him in that old alley.
He guards her past and her present,
But he endured it alone:
He remembers everything, but she forgets him.
When the memories are finally pieced together, life is counting down.
This reunion is a life-long bet,
It ended with a burial at sea.
Time has passed and it's time to return to the appointment.
In this life, you forgot about me. In the next life, I will find you first.
Intention: Love is the only faith in a desperate situation, an obsession that cannot be separated by life and death.
