I'm looking for a manga I read. It's about a young woman who's grandfather, who's a king, just died. She gets a letter that tells her she's one of the heir. She needs to go through the next king selection. She finds herself with 3 man who are also selected to be candidates. All 4 needs to vote for the next sovereign however they can't vote for themselves. So they have to convince the others to vote for them. Anyone knows the name of that manga? I read it on mangadex I think. Thanks!
