If you liked the Skip Beat! manga, the Anime-Planet community thinks you'd like:
Four gorgeous guys, one fabulous mansion and one challenge - turn the landlady's niece into a perfect lady and live rent free; fail and their rent will triple! Surely this task will be no problem for Ranmaru Mori, Kyouhei Takano, Takenaga Oda and Yuki Tohyama, who are lauded as the princes of their high school and have girls dropping at their feet daily... right? The boys' dream of rent-free living comes crashing down when they meet Sunako Nakahara, the girl they must transform. Sunako has devoted her life to solitude, preferring the company of anatomy mannequins, horror movies and the darkened seclusion of her bedroom to the presence of the ‘dazzling creatures' that cause her to have violent nosebleeds. Flushing her out into the light might prove to be more than the boys can handle!
Both mangas center around a girl who completely changes due to one guy. In Skip Beat, it is a guy who has used and led Kyoko on since they were kids. In Wallflower, it is a guy that Sunako likes who tells her she's ugly. Both mangas are VERY FUNNY, relying on the main characters' somewhat dark sides to be a driving force. In both mangas, the main characters are afraid to fall in love/ avoid love at all costs because of what they have experienced. Truly, both mangas are about one girl's trials and tribulations on her journey to rediscover what love and life is. Oh and both feature really attractive guys, as an added bonus.
The government has passed the Media Betterment Act, establishing a military police force to stop the spread of "negative influences harmful to society;" and in response, libraries have organized their own military units to protect freedom of expression. After being saved by a Library Defense Force agent in a bookstore, Kasahara is inspired to enlist in the Library Defense Force. Although she proves quite athletic and capable, she must endure the harsh but meaningful training of her instructor and superior officer, Doujou. As she learns how to be a good soldier, she participates in LDF operations, helping protect literary freedom for everyone.
The female protagonists in Toshokan Sensou Spitfire! and Skip Beat have an upbeat personality even though their current situation may be relatively bleak, they always see the sunshine at the end. They strive to make it to the top of their respective fields as the main male characters help them along the way without the female characters knowing.
