[Machine Translation] The second single from Office Augusta's big newcomer, Yohhei Hamahata, is a delicate, piano-driven ballad! The coupling consists of a beautiful acoustic guitar ballad "Sayonara Lullaby," an R&R number "Driving on K" recorded with the band members at his debut live concert, and a song completed by Yohhei Hamahata himself with multiple recordings of all the instruments. The first limited edition DVD contains four songs that are full of new charms and topics. The DVD of the limited first pressing will include "Muyakuyaku" and "Yui" from the live performance at Daikanyama UNIT on December 9, 2014, as well as other highlights of the album, totaling approximately 30 minutes.
