Next, the main male characters of both mangas share similar characteristics. Last, the development of the relationship between the two main characters. The female characters both have a 'Do I? Dont I?' attitude towards the male & the obstacles in the relationship are also similar. ^.^
Both series have a heroine who has to deal with a romantic interest who starts off as a bully. Because of the social differences between the characters ("You can't stand up to him! Don't you know who his mother is?") they have the same kind of feel a lot of the time, and both series have more romantic interests turn up along the way.
