Both mangas feature an orphaned girl who suddenly finds herself being doted on by older men, brothers in Onii-chan to Issho and butlers in Himegimi no Tsukurikata. In both cases, the stories are cute and the characters total eye candy ;)

Both animes share the same premise, a boy, not especially popular, suddenly finds himself surrounded by girls interested in him. A lot of the visual gags usually arising from misunderstandings, which result in the boy getting beaten up and called a pervert, are also present in both series.
