The story is set 10 years after the F4 and Makino Tsukushi featured in "Hana Yori Dango" had graduated from Eitoku Gakuen which is facing difficulties due to declining enrollment as a result of the recession. Sugisaki plays the lead character Edogawa Oto who attends Eitoku despite being from a poor family while Hirano plays Kakuragi Haruto who is the heir of Kakuragi Group and regarded as the 2nd Doumyouji in Eitoku because of his leader position in C5 (Correct 5) even though he is actually weak mentally and incompetent. Nakagawa will play Oto's fiance Hase Tenma who is the student council chairman at Momonozono Gakuin, the rival school of Eitoku.
Sugisaki said that she was very surprised and happy to be given this chance especially since the title of this drama also had her name "hana". As such, she pledged to put in her best effort to play Oto. As for Hirano, he said that he had watched the original Hanadan series back then in 2005 and 2008 starring Inoue Mao and Matsumoto Jun when he was a student so he was extremely happy to be given this chance. He hoped to do his best so as not to disappoint the original manga's fans. Last but not least, Nakagawa said that the only time when he got into a quarrel with his parents was when he didn't manage to record the last episode of the Hanadan drama even though he was a faithful fan of the series. He was filled with a lot of joy when he got the offer to star in the sequel and hoped to play Hase in a convincing manner.
