Michiyo said in an interview a few months after the release:

I really like the song because it reminds me of springtime. When I was asked to join the unit, I couldn’t believe it. But it was a great opportunity for me to be a part of a major project by Hello! [NB: old name for Hello! Project] , as well as learning new choreography, which I never get to do as a solo artist. I also liked the fact that I was able to listen to other member’s vocals in a close proximity, so I’m glad I did it.

Tsunku’s comments:

"I’ve held a special event for those who have been very supportive of Michiyo Heike, Morning Musume, Taiyo To Ciscomoon, and Coconut Musume. It’s like an event to return favors to the fans. Last summer and this January, we’ve held the collective concerts. I felt very special when I saw the members who seldom saw each other gathered together and made efforts to create one great show. My theme for this time is, “How do I express the same energy into the sound?” The unit consists of Michiyo Heike, Abe and Yasuda from Morning Musume, RuRu from Taiyo To Ciscomoon, Ayaka from Coconut Musume. Normally, they are considered as the skilled vocalists in their own groups. By putting them together in one group, more competitive, energetic and stimulating atmosphere was created. This unit is about soul-classic dance music. In another words, I’ve combined the good quality of Morning Musume and Taiyo To Ciscomoon together. When you listen to their song, you’ll feel like having lots of fun. They have really good choreography as well."
