30-Year-old Lin Shen has accomplished nothing - he is a low-level copywriter in an advertising company, with a monthly salary of just over 10,000 yuan. He lives alone in a rented house with no lover, no friends, and no future.
While working overtime late at night, he had a heart attack and his heart stopped for three minutes.
In those three minutes, he traveled through time.
He came to another parallel time and space, and met another version of himself - his parents died young, he lived the same thirty years of life, but he lived like what he "should have been" in his dream: a top designer in the industry, the founder of a successful company, with a beloved fiancée and a warm family.
72 Hours. This is the time he can stay in that perfect world.
He thought it was a joke of fate, a cruel comparison. But when he discovered that the divergence between the two time and spaces was actually only a tiny thing - a word, an action, an outstretched hand - he suddenly understood that this was not an arrangement of fate, but his own choice of mediocrity.
What's even more terrifying is that in 72 hours, that perfect Lin Shen will disappear forever.
Unless——he made the choice for "himself" that was fifteen years late.
