Looking for a Book Like The Ghost Who Worked at Empresses in the Palace

Looking for stories similar to The Ghost Working a Job in Empresses in the Palace. Just like the title says, I'm looking for similar quick transmigration stories. Don't change the original character's appearance, and don't have them start by taking beauty pills. Ideally, they should stay true to the original character's personality. A few changes are fine, but don't change too much.
