Otomen is a delightful series! I own the first book (of 18).
Otomen focuses on the trials and tribulations of high schooler, Asuka Masamune, who has the manliest or manly traits--and looks the part--but is also, secretly, utterly enamored of pretty, cutesy things. He enjoys sewing, making gooey desserts, and quiet strolls along the beach. He is the antithesis of the amusing Tim Taylor.
The conflict arises from his social role versus his inner self: that is, how society perceives him versus how he really is.
The problem of social perceptions is cleverly done: BIG EVIL MINDLESS SOCIAL ASSUMPTIONS do not cause his problems; rather, tensions arise from the personal assumptions of people whom he adores, likes, and wants to impress. He has to fight to be slowly accepted by a lovable coterie of friends: the girlfriend, who accepts him entirely as he is (and occasionally rescues him); the manga artist, who uses him as fodder for his shojo; the guy who loves flowers; and even the Moe guy who wants passionately to be Mr. Manly himself.
As in all good Japanese shojo, the group expands to include others, including Asuka's so-called rival who is secretly also an otoman, preferring a future of applying make-up to the business dealings of his family.
One of the entirely fun aspects of Japanese manga is the 1950s-like thoughtful struggle against conservative roles. Due to American flexibility and constant change, American plots have to designate blame in order to produce the same struggle--the avant-garde artist rebelling against his fundamentalist, cult parents, for example--and the outcome is often far less harmonious and comprehensive than that found in manga.
Which isn't to say that both conflicts aren't fictionally contrived. Still, it is preferable to read about a sweet boy trying to find his place in life than an angry, rebellious teen telling everybody, "You stink!"
Otomen is about the sweet.
