[Everyday life + romance + one female lead (maybe) + sci-fi (Liu Cixin would quit the sci-fi world on the spot after reading this)]

(The author's writing their first novel, so the prose might not be great, but there definitely won't be any brainless plotlines.)

One day, Su Cheng discovered a second voice in his mind. After talking with it, he learned it was his future self.

With his future self's arrival, Su Cheng's life took a different path.
