What's going on! !
Fifteen minutes, another fifteen minutes!
No matter where he is, Yang Dai will sit back in the classroom safe and sound after every fifteen minutes, and will return to the moment when the physics exam is handed in! !
Has time abandoned him? Or is he out of time? ! Do you want to be stuck in this boring joke for the rest of your life without even being able to end it on your own? !
Impossible!
Then,
Let him see what happened in the cracks of time.
Let him see what two people who depend on each other in the gap of time will discover.
Show him how to escape from invisible and intangible enemies.
Like tigers and leopards ready to attack, they fight silently against time.
