Jean P. Mayol (ジャン・P・マイヨール,Jan P Maiyōru) was a French politician and a potential candidate for presidency. He proposed to former Japanese heiress Shizuka Todo, but was turned down. Rumors that she accepted his proposal spread around France and Japan.
Jean was a popular politician in France. He was rumored to be a candidate for the French presidency. Jean proposed to the Japanese heiress and model, Shizuka Todo. His proposal was widely reported in the French and Japanese tabloids. The reports also said that she had accepted. However, Shizuka had actually turned him down. Her reason was that she could not picture herself marrying someone she did not love.
Jean was a handsome, young Frenchman. His overall features were likable and well-proportioned. His short, light hair was slicked back likely with hair gel. He was seen wearing a nice-looking, expensive suit and tie.
Shizuka goes on to marry a Frenchman in a special chapter. Though unnamed, the man is a lawyer which confirms that he is not Jean.
He is mentioned in Hana Yori Dango: The Musical (2016). In the musical, Rui appears to be more jealous of Jean than is shown in the manga. He eventually leaves France because of Jean.
In the musical Hana Yori Dango (2019), Jean is mentioned a couple times. His personal details are kept the same, except Shizuka does not deny them being engaged in this version.
In the episode "Night of Betrayal" of the Boys Over Flowers anime (1996), Jean is seen in a photograph with Shizuka. Everything from his appearance to his personal details are kept the same. Unlike in the manga, Shizuka is never seen denying that she has or had a relationship with him. However, as it is a tabloid story, it is equally unlikely to be true in the anime. In the English subtitles, his name is spelled "Jean Paul Mailleur."
He is briefly shown in a few photographs of a magazine in episode seven of Hana Yori Dango (2005), played by an unknown actor. His appearance is similar to the manga as well as the details mentioned about him. It is assumed that Jean and Shizuka being linked was a rumor as she returns for Rui in the finale.
