Reborn, I Send My Scumbag Ex to Prison Myself

I’m Out of Books to Read. What Are Your All-Time Masterpiece Recommendations?

Quick transmigration, interstellar, or cultivation novels are what I'm after, though modern settings are fine too. No variety shows or livestreaming. I prefer stories focused on the female lead, and I want a happy ending. A System is optional. If there is one, it shouldn't have too much of a presence. If it does, it shouldn't be useless; I just read a novel with a useless System and I'm exhausted.
