Reborn in the Nineties, Carried to Success by Grandpa

Cheng Yu died for no apparent reason, and came back to life for no apparent reason, too.

She was a perfectly healthy adult, with no regrets and no wrongs to her name, yet one day she suddenly died of a heart attack.

When she woke again, she was back at the age when she couldn't yet control her bowels.

Well, since she's here, she might as well make the best of it.

All she has to do is live through her once smooth-sailing life all over again.

But... now that she has another chance, could she change her grandparents' fate just a little, so they don't leave this world so soon and so easily?

Just as Cheng Yu was preparing to sharpen her knives and go after her uncles, aunts, and cousins, she suddenly realized that her grandpa Wan Hua's bamboo switch was much faster than the grand ambitions of a toothless little girl like her. Those ungrateful wretches were all getting thrashed until they squealed.

As her grandparents' favorite "little granddaughter," could she maybe, perhaps, just lie flat?

P.S. 1. The female lead knows her grandpa has been reborn, but he doesn't know she has been reborn.

2. The old man goes on a rampage, while the female lead lies flat. This is a satisfying story with no frustrating angst. The female lead takes her grandmother's surname, and Wan Hua is her grandfather.
