Reborn but still slow on the uptake, Shen Beiyi & scheming Sheng Xing

Shen Beiyi was reborn, returning to the first day of her second year of high school.

In her past life, she had hesitated and missed out on so much. She went from twenty-six back to sixteen, crossing ten years in reverse and gaining the chance to redo her life.

Little by little, she reclaimed the things she had once lost.

But where did this new person suddenly come from?

Sheng Xing argued confidently, "I was something you lost, too. Can't I come looking for you myself?"

Shen Beiyi: "Wait a second, aren't we rivals in love?"

Sheng Xing: "?"

Shen Beiyi: "?"

A story about rivals in love becoming lovers, with a touch of mistaken assumptions.

Reading guide: Two idiots (crossed out), beginners at dating, bickering like grade-school kids.

Their feelings never cause anyone else any trouble.

Thesis: The unexpected newcomer beats the childhood sweetheart
