Searching for manga

Losing favorited manga list is insane. I could feel less sad if someone can help me find a particular manga (not webtoon)


Type: shojo
Context: noble at school
Description: a group of noble girls is meeting misfortune (not really) due to a priestress from poor background. Rude and stick the male character. But what we are is seeing is that the girls, inspired by the prince's fiancee natural noble stature, don't need the man to be grand. First girl broke up with its fiance to end up with the fiance's little brother. Second girl will be replacing its good-for-nothing brother but needs to overcome that patriarcal family (latest in progress)
