Want write to producer or writer of show please

Hi I was wondering if someone canhelp me find the producer or writers of the show as would like to use the Sunflower information in a teen romance book I am writing. I found this interesting about the number of Sunflowers had different meanings. I am based in New Zealand and really loved this show and are looking forward to the second season. It was great to see Japan at its finest as never travelled to there yet. It was one of the sweetest love reality shows I have seen and thoroughly enjoyed it. Thanks L
