Golden Japanesque and A Sign of Affection are two modern shoujo manga where a romance forms after the male lead meets the female protagonist and causes her to essentially open up from her otherwise kept-to-herself life. Language and/or language barriers are bit of a common theme, whether it be between Japanese and English, or spoken and sign language. The dynamics of the relationship are pretty different (especially when Golden Japanesque is very much a drama), but both series have rather wholesome romantic development.
