I'd recommend Glass Mask by Suzue Miuchi. It was out in the early 1970, and it's still ongoing. Fans of the manga are urging the author to finish the manga before they die
. The story is about a 13-year-old girl named Maya whose only passion is acting. She went through a lot of trouble to continue her acting career, with the secret support of Masumi, the President of a huge company, whom she hated the most because he always appeared to be cold and cruel to her. Things started getting interesting and complicated when Masumi fell in love with Maya. The rest, you should really read the manga to find out.
