Both protagonists are reincarnated as the villainess of an otome game they once played, and end up in another kingdom. They both end up being the love target of the princes in that kingdom as well, without them knowing (one-sided love, at the beginning at least). While Akuyaki focuses more on the romance and sweet moments between the two, Tensei-saki is also about the MC having fun cooking.
Both works are otome game isekais with shoujo demographic.
