At first, they just "borrowed each other's fire" - Shen Du gave Lin Shi the half-box of milk he picked up, and Lin Shi finished writing the English tasks required for power leveling for Shen Du. Later, they worked part-time at the snack street until early in the morning, and shared a military coat to do homework in the cold winter.
No one thought highly of them: the teacher said, "You will destroy yourselves if you do this," and the co-workers laughed, "What future can two men have?"
But they really went from the age of eighteen to twenty-eight, from the partitions of the rental house to the courtyard they designed themselves, from being unable to pay the water and electricity bills to one of them becoming an architect (Lin Shi), and the other opening a chain of auto repair shops (Shendu).
He experienced the most difficult moments in the process: Shen Du almost went to jail for fighting, Lin Shi gave up his postgraduate scholarship and went to work outside the city to collect bail money; Lin Shi was diagnosed with hereditary heart disease, and Shen Du sold the second-hand truck he had just saved up to buy.
But every time, they looked back and found that the other person was still there.
Intention: Picking each other up at an age when we have nothing, and never being separated in the years when we have everything - It turns out that the best love is when you are surrounded by the same person from beginning to end.
