i read it on the official site but i also found it on
https://wuxiaworld.site/novel/the-villainess-turns-the-hourglass/

The story is quite long and a lot happened so I'll just spoil some events and you can ask from there.
Aria plans to seduce Oscar, the guy Mielle is to be engaged with (there families were already talking about it but there was no official engagement yet iirc).
Aria meets the Crown Prince when he was out in town incognito investigating.
Crown Prince thought that the woman he met in town (while he was incognito) was Mielle since Aria was wearing Mielle's dress.
The hourglass is not a one time deal. Aria gets to keep the hourglass and she can use it once a day and turn back time 5 minutes before. Backlash is that she gets very tired and she needs to sleep longer.
Crown Prince also has some hidden powers.
Aria is not in anyway related to Mielle, her brother, and their father. Aria was borne from one of her mother's customers. He will be introduced after Mielle's house is ruined.
Mielle is not the endgame villain. Another girl will be introduced. She is Oscar's sister and the Crown Prince's fiancee.
Because of the hourglass, Aria makes contributions to her father's business. A frustrating misunderstanding occurs.
Aria earns money for herself by investing in start-up companies. She earns a name for herself as Mr. A. Young businessmen come up to her to fund their companies cuz every company she invested in was successful.
There's politics in the story. Royalists and anti-royalists. Crown Prince's fiancee's family is in the anti royalist faction. He's supposed to marry her so there will be power balance.

thank you for spoilers I really look for it almost everywhere (I still don't have any chance to read the novel yet and I guess my free-time is not enough for the long novels yet) may I ask one question: when the crown prince knows that he has mistaken Aria with Mielle and what's his reaction from that.

SPOILERS
The big reveal is when Aria attends the bday party of the evil sister lol. He came up to Aria and asked her if she really wasn't Mielle hahahaha He walked out of there.
Preciously, he asked his aide to pretend to be a businessman and help Aria's father. When the aide went to their house he praised Mielle for being intelligent and helping her dad's business (this was the misunderstanding, it was actually Aria who did that but the dad didn't correct the aide). So the nxt time the aide came, he brought gifts for Mielle from his master. This was actually the crown prince's way of wooing Aria but hahahha he was wasting his time and money on Mielle instead.

SPOILER
Aria pretended to help Mielle and she was doing it so seriously too that Mielle actually believed her. There was no doubt in Mielle's mind that Aria was deceiving. When Mielle was supposed to be beheaded, Aria did the same thing to her (like what happened in her past). She talked to Mielle (in a voice that only they could hear) and told Mielle the truth about the hourglass and everything else like how she knew about Mielle'a schemes. Mielle kind of lost it at that moment.

SPOILER
Aria's grandmother was a royal (but I think it was a branch family). She later married the love of her life from another kingdom (iirc). So Aria has royal blood. Her dad was the heir to a noble family. Both grandma and dad are permanently living in another kingdom. Dad's name was Chloe. He was actually looking for Aria's mother since before but she was using a fake name when she was a prostitute (i think it was Apple/Cherry) so he did't find her
Just read the novel last January so everything is still fresh in my mind hahahah and now this! Love it!!! Aria's whole revenge story was fucking glorious. She's indeed a strong independent woman.
