Yu An'an, an ordinary girl, has been secretly in love with the male god Li Fei since middle school. However, by mistake, she ends up with Li Fei's good friend, the top student Lu Nian. During the six years they were together, they gradually grew closer. However, three years of being apart made them miss each other's best years. When they found that they fell in love with each other, they discovered that the so-called beautiful love and friendship were actually full of calculations and conspiracies from the beginning. The harder they try to get closer, the further they are pushed away by the flow of time. When love faces the test of friendship, morality, time and distance, how should they choose? From the distance of three tables at the beginning to the distance of a pair of hands, they kept getting closer, but were pulled away by fate, and finally settled on a distance of 1.5 Hours, which can never be crossed.
