At the age of 18, Huo Youqing unexpectedly wakes up in the body of his 27-year-old self, leaping nine years into the future where everything around him has changed.
His childhood best friend, once closest to him, now grips his throat, punches him in the face, and curses his ancestors.
His college roommate, who used to dote on him, looks at him with pure hatred.
From their words, Huo Youqing learns a name—
"Dai Yuan."
They all despise him because of Dai Yuan.
Huo Youqing doesn’t know Dai Yuan.
Assuming he has lost his memory, Huo Youqing calmly accepts the shift in people’s attitudes—until he wakes up again.
He’s back at 18.
The same childhood friend who, moments ago, wanted him dead to avenge Dai Yuan, now bends down, tenderly caressing his cheek while softly coaxing him:
"Sleeping here is too cold. Youyou, let me take you home."
The college roommate who once said he’d face retribution kneels before him, carefully applying a band-aid to his foot, murmuring earnestly:
"Youqing, you have a small cut on your foot."
From then on, Huo Youqing begins to shuttle between these two timelines.
