Reborn, I Just Want to Live to a Hundred

Su Que always believed that when in a world, one should follow that world's rules. So she took the usual path for a noblewoman: married a man, treated him with mutual respect, and didn't object when he took concubines. As long as she was happy, she didn't care.

That is, until her husband found true love and ruthlessly tried to kill her.

Absolutely not. If he wouldn't let her live, then they could all go to hell together!

But before the gates of hell opened, she found herself back in the sunlight, returned to the year she had agreed to marry.
