Fan rec - MM。 FC Tour Mini Live in Hawaii 2012 「Speaking of Hawaii, there are so many memories of me and Eri and I would like to sing this song so, I send mail to ask Eri. Eri who only reply mail occasionally had replied immediately, "Sing it. Sing it. Sing it." she said.」 During MC (not in the video), Sayu also said that she wanted to sing this song for Eri fans. She is sure there must be Eri fans in the event as well.
