Due to a time and space confusion, Gu Zhihuan met the young Yu Ge in a dream, and picked up the blue love letter he left behind. At the same time, she bumped into Yu Ge from 2018, and was involved in a cross-time and space adventure to save Yu Ge. She found out that Yu Ge died in a laboratory explosion many years ago, and determined to reverse the tragedy, she went back to 2009 with Yu Ge and rescued him as her sister. After the timeline was restored, Yu Ge forgot everything, while Yu Ge mistakenly thought that Lin Zhiwan was in love with her. The ensuing exchange of consciousness and Lin Zhiwan's entanglement have not yet subsided, and the remaining turbulence of time and space has trapped Gu Zhihuan's consciousness in her childhood. Yu Ge and Yu Ge crossed the twists and turns of time and space and finally regained her consciousness. However, Gu Zhihuan's memory of this love in time and space has been completely cleared. The gray-haired Yu Ge could only look at the still bright girl from a distance, letting the fateful white space sway gently in the wind.
Purpose: This article uses the chaos of time and space as an opportunity to tell the story of Gu Zhihuan's adventures in reversing the tragedy of the laboratory explosion and rescuing Yu Ge as her sister through the cross-time and space encounters between Gu Zhihuan, the young Yu Ge, and Yu Ge in 2020. In the multiple twists and turns of consciousness exchange, memory erasure, and turbulence of time and space, it explores "the price of love and redemption" and "the inevitability of self-growth", conveys the core belief that "even if the memory disappears, sincerity and protection will still leave traces in time", and shows the protagonist's transformation from ignorance of redemption to calm acceptance of fate in the choice across time and space.
