As usual with the Johnny's groups attached to Avex the single has three versions, two LEs with DVDs and a RE. The difference between the LEs is the first has the PV and making of while the other has solo versions of the PV for the two members. The RE comes with two songs that are not on the LE versions.
So it's not a bad year for the duo compared to the past couple of years. As this will bring them to having a mini album and a single released in 2011.
