Lin Xiaoshu is an ordinary third-grade boy who always wants to exchange his idle time for good grades and his boring weekends for victory in games.
By chance, he discovered a mysterious shop on the corner of the street - Time Store.
Granny Shi, the store manager with silver hair and strange eyes, told him.
"Every time has value, every choice has meaning, and stories related to time can be traded."
From then on, Xiaoshu had an hourglass that could exchange time.
Trade your lunch break for homework, trade your weekend for victory, trade your daze for rewards...
At first, the deal seemed like a good deal.
But he soon discovered that behind every seemingly good deal, there was an unexpected price hidden.
The time that has been exchanged will come to collect debts at the most unexpected moments, and those seemingly useless times carry his most precious memories and feelings.
From frequent transactions to learning to cancel, from cherishing alone to helping others, Xiaoshu and his friends are under the guidance of Granny Shi.
Gradually I understood a secret: time is never traded, but cherished.
And those cherished time will become the eternal shining transparent sand in the hourglass, which is a treasure more precious than any transaction.
