Full Moon wo Sagashite, Glass no Kamen (2005) Recommendations
In both the main characters are teenage girls who work hard in order to make their dreams come true. In "Glass Mask" Maya wants to be an actress and in "Full Moon" Mitsuki wants to be a singer. Both are Shoujo and also contain romance (of course)
Starting off light and becoming more serious later, these two are really good stories about pursuing show biz and your dreams. They both have sweet romance, talented female leads, some humour and great stories . . . watch these two!
Both talks about a female protagonist being supported by many people around them, they both include some kind of way to making it to the top, both are highly emotional though i found full moon wo sagashite closer to the sad side.
