The LDH girl groups, Happiness and Flower will be releasing new singles on the same day. It is so the two groups will compete against each other for number of sales. Both singles will have three versions of the singles. A limited edition with a DVD, a regular edition and then a special limited edition which will only cost 500 Yen (a "one coin single" as these tend to be called as the largest coin amount in Yen is 500) that will only have the title track on it.
Happiness' single will be called Sunshine Dream - Ichido kiri no Natsu and both the LE w/DVD and RE will have the B-side Boyfriend (Sunshine version) on it. The LE w/DVD though has another track, Eien, on it as well.
Flower's single is called Taiyo to Himawari and both the LE w/DVD and RE will have the B-side Boyfriend (Moonlight version) on it. The LE w/DVD though has another track, whose title has not been revealed yet, on it as well.
Both groups will be doing a series of small concerts across Japan when the singles are released to promote them.
It will be interesting to see what the outcome of this will be, especially as Happiness has added two members to the group, which includes another vocalist. If anything releasing the singles like this will help the group garner some extra attention as well as getting their fans to want to make sure they pick up a copy of the single for their favorite group.
