Ares

I was reading a story about a duke's daughter who was captured by the second prince who's trying to start a revolution. In her first life the daughter didn't even know her name and was sent on a mission to kill her parents. Now that she's reincarnated, she's still going along with the second prince's (he has red hair) orders but cooperating with the current king's son (black hair golden eyes). It's kind of a recent manhwa but I lost it in the crash, please please please help!!!
