President of the Student Council at the almost-all-boys Seika High School, the hard-as-nails Misaki Ayuzawa works every day to make life easier on the small population of co-eds who have enrolled there. Though an unholy terror to all things male during school hours, in order to provide for her impoverished family, she secretly works after school at a maid cafe in Akihabara. However, when campus hottie Usui Takumi wanders into the restaurant during her shift, suddenly she finds her reputation in school at his mercy...
Kyoko moves to the big city with the prince of her dreams Shotaro; he wants to make it big in the entertainment business, so she works hard at many different jobs to support him as he achieves his dream. However, one day, Kyoko accidentally discovers the horrible truth: the love of her life thinks of her as a 'plain and boring woman!' Outraged, Kyoko swears revenge - she will make it even bigger than Shotaro in the entertainment world. The only question is, how will she fulfill her desire?
The female characters in Skip Beat! and Maid-sama! are hard working girls that are a little down on their luck. They are extremely determined and will do whatever they have to do to succeed and obtain their goal. Each involves a little bit of romance and some comedy thrown in.
After the death of her parents, Tsukasa turns to her classmate Ryuji, a yakuza boss, for shelter and a job. Ryuji is generally grave, but purposefully indebts Tsukasa to him so that she has to keep working for him, and he can keep his friend near him. Tsukasa is a simple-minded girl who desperately searches for money to pay off her debts to Ryuji. To make money, she takes on suspicious jobs in addition to being Ryuji's bodyguard, but always ends up in trouble. Ryuji and Tsukasa take turns saving each other as they fight together against the spread of dangerous drugs and weaponry that would destroy Tokyo even more than it has already degraded.
Again, both mangas feature a more assertive female lead, different from typical romance mangas where women are often portrayed as weak. Although the context of TCP (yakuza) is very different from KwM (high school), both have a lot to offer in terms of humour, butt kicking, and general girl power.
These two have lots of similarities from tags to story plot. Both are Rom-Com Shoujo and have female main characters think of the male main characters as their rival. Male main characters have a mysterious personality and annoying attitude when the talk comes to their family/past.
Both series have strong, independent female character and handsome, skillful male character (to the point of having fans). Girls both have no clue about dressing-up feminine, have got violent but also warm and responsible personality and are quite dense with realizing their feelings (even if there is a feeling in everything they think or do). I the other side guys are totally in love with the one and only girl and are willing to do anything for them.
There is also a misunderstanding between father and son in both.
So I think that if you like one, you will like another :)
Daichi Shinigawa is a typical delinquent who wants nothing to do with high school. However, bespectacled Hana Adachi, the class representative, will do anything in her power to make sure Daichi participates in whatever events the school has to offer. If she has to surprise him in the boy's bathroom to get him to go on the school field trip, so be it! Daichi is confused as to why a class rep would care so much about a troublemaker like him; what could be the reason behind her actions?
Both Kaichou wa Maid-sama and Yankee-kun to Megane-chan are about hard working high-school student councils. One is a shojou manga while the other is a shonen one, so the style does differ, but if you enjoyed one of these you will probably like the other too. I mean both have bits of comedy and romance, what's not to like?
P.S. YtM starts off weak, but gets better around volume 2 with introduction of new characters. Because of that the resemblance is not obvious from the start.
