Does someone know the title of this

So I remember this manga that i read back then, the setting is in a otome game world where one of the mc gets framed for something so that the other girl could steal the crown prince. There were three mc iirc(the fiance of crown prince, a dukes daughter and another noble’s daughter who was rly shy). And i rmbr the manga is also abt the other girls thats why i rmbrd it
