Yuan Hua, 28 years old, is the only car aroma diffuser designer in China. Her job is to repeatedly calculate the millimeter-level holes - if the hole is too large, the pungent aroma will evaporate too quickly, giving the car owner a headache; if the hole is too small, the aroma will not come out, and it will be like a fake. She wants to find the "just right" aperture.
On a blind date, she met her high school classmate Shen Huai. The boy who would help her block the crowds in the hallway ten years ago has now become a critical and demanding automotive interior engineer. The two met again because of work. He pointed out the flaws in her design without mercy, and she argued with reason and refused to give in.
The secret love ten years ago and the reunion ten years later are sandwiched by a series of technical difficulties: essential oil leakage, bumpy driving, disordered fragrance production, and out-of-control constant-temperature fragrance diffusion... Every technical breakthrough is a step closer, and every failure makes them realize that life is like the fragrance hole. Too fast will be overloaded, too slow will be dull, and only the right time can retain the right person.
This is a war about 0.1 Mm, and it is also a long wait of ten years.
