Hu Dan and Liu Mo were high school classmates and had spoken no more than a hundred sentences in ten years. If it hadn't been for the engagement party of their mutual friend Lin Wei, they might have been the same name in each other's address books forever.
On the way back in the car, a joke "How about you see how I am" made the two adults decide to "try it". They originally thought that falling in love as an adult is just a matter of weighing the pros and cons. But when I got closer, I discovered that there is a problem in the world called "I like you, but our lives are in different time zones."
Hu Dan dared not promise the future, and Liu Mo longed for a definite answer. When love stands at the critical point of a joke, taking a step forward is a responsibility, and taking a step back is a regret. They must answer a question: If two people see the future differently, are they still qualified to love each other?
This is a story about timing, courage and adult choices.
