Back to the Past: Starting by Saving a Girl with No Personality

The thing Xu Zeyou is probably proudest of in his life is that two campus goddesses remember him.

One is a blank-faced girl who once exchanged gifts with him. She died eight years ago.

The other is an elf girl who called him after eight years, though she seems to be in poor health.

But after answering that call, Xu Zeyou was accidentally killed by a runaway truck.

By chance, he triggered an ability hidden within him: the gift he had exchanged with the blank-faced girl in his class eight years ago.

It let him travel through time and return to the past for seven days.

After going back, he gradually discovered that the blank-faced girl's death might not have been an accident. It seemed to have been a planned murder all along.
