Marmalade Boy - Production

Production

When Wataru Yoshizumi first started planning Marmalade Boy, with Miki, Yuu, Ginta, and Meiko all the opposite genders of what they ended up being in the final versions. The original Miki looked similar to Yuu's final appearance, while Yuu was an attractive girl with long black hair and a "devilish" and "unpredictable" personality. Yoshizumi notes several reasons behind the changes. Part of the reason was that it was a request from the Ribon publishers, who wanted a female as the central character as the story was going to be included in a "Mother's Day" set with magnets featuring the characters. Her associate editor also expressed concerns that a male hero would be a "sissy" when written about by a female writer. Finally, Yoshizumi herself decided that she would go with a heroine rather than a hero as most of the Ribon readers are girls.

In the original story, the title of Marmalade Boy was an indication of the hero Miki's cheerful, sweet, and naive nature. After redoing the concept, she wanted to keep the original title, changing its meaning to what is stated in the first volume, that Yuu "has lots of bitter bits inside" him but people only see his sweet surface.

The ending for the series was also very different from the final version. Ginta and Arimi were not going to be a couple in the original version, nor was Meiko going to be reunited with Namura. Yoshizumi originally intended for Miki and Yuu to truly be blood siblings, and thus have to break up. Afterwards, Ginta would comfort Miki and promising to wait for her to get over Yuu. Yuu and Meiko would have been shown meeting four years later, having both having failed in their previous relationships. The ending would have been more open ending so readers would have had to wonder what really would happen to everyone. However, as she was writing the third chapter, Yoshizumi became less certain of the ending, as it made Miki and Yuu's parents appear to be awful people for doing such a thing to their children. She also was concerned how readers would react, and her own feelings of "emptiness" at the sad ending. Her editor agreed that the ending would be bad, so she changed it to the happier one now found in the series.
