So glad I found this site
Love LDH and Flower is my favorite group <3 They recently finished their tour, but I'm still itching for more Flower
I'm in love with the song nanairo candle. I think it expresses the connection between the seven really beautifully
Also, I found this on dailymotion:

I think it's supposed to be a recording of Shuuka playing on the piano for the song "Hasukoi" during one of Flower's live performances.
