Kobushi Factory performed their new single "Seishun no Hana"
Lyrics and Composition by Hoshibe Sho, Arranged by Miyanaga Jiro (Both of them worked together on Kobushi Factory's "Shalala! Yareru Hazu Sa" and "Naseba Naru". Weird enough, both songs were created during Kobushi Factory's tough times).
at the Night concert ~side A~, Kobushi Factory also performed their new single "Seishun no Hana"
"Seishun no Hana" is described as a hip-hop-style medium ballad. The members face each other and sing in harmony
