Eighteen-year-old reclusive science and technology genius Lu Yu × Thirty-two-year-old single-parent working woman Su Wan
Everyone said that Lu Yu was a physics genius who was born out of nowhere, and he had the entire galaxy of science and technology at his young age.
No one knows that he has devoted himself to physics and endured his obsession alone for nine years, all for Su Wan.
At the age of eighteen, he put away his trillions of net worth and pretended to be an intern to get close to Su Wan, who was raising a child alone and working hard with a heavy burden.
He hid the past of being saved by her when he was young, and was willing to be her nameless support behind her, carefully giving all his preference to her.
He plucked up the courage to ask for his lover's status, but she never dared to agree due to the age gap and practical concerns.
The two were together day and night, and their warmth lasted forever, but there was always an identity gap that couldn't be crossed.
Until the end of her life, he traveled through thousands of desolate planes, traveled through countless parallel times and spaces, and spent his whole life searching for her against the will of heaven.
Years of waiting in vain, year after year of failure, just for a belated reunion to keep her safe and worry-free for the rest of her life.
