The idol star also mentioned how B1A4's music style had changed since their previous album, saying, "We either went with 'I'm so happy' when falling in love or 'I''m so sad' when breaking up but this time we went for the strong feelings of falling in love. I think our style has changed a bit."

In regards to their future expectations, B1A4 added, "'Rollin' received good feedback so we're looking forward to it even more now."  Shinwoo also stated, "We have a lot of things planned so please stay tuned."
