In the finals three years ago, Lu Zhaohan missed the championship in a single thought, and personally ruined the possibility of reaching the top with Shi Lin. In the early hours of that night, he was so remorseful that he accidentally restarted time - back to 72 hours before the game. This time, he no longer evades or hesitates, and vows to change the outcome. But when he faced Shi Lin's cold and distant eyes, he was shocked to realize that the other person had already seen through everything.

Besides winning or losing, what are they fighting for?
