Group INFINITE staged a special performance of "Sonagi" on the June 13 show of KBS "Music Bank".

INFINITE staged their comeback show on "Music Bank" after 4 weeks of album release due to the program's cancellation. INFINITE staged their first performance of "Sonagi" along with their title song "Last Romeo".

"Sonagi" is made based on the famous novel of the same title by Hwang Soon Won. The song features a string and guitar sound that serves to intensify the song.

"Sonagi", last track of new album SEASON 2, is as popular among fans as INFINITE's title song "Last Romeo".

Wollim Entertainment stated: "We were planning to surprise fans, and decided to stage "Sonagi". It will be a different but awesome stage".

Previously, INFINITE had received the first place trophy five times for their song "Last Romeo" on several music programs, including "Music Bank" on May 30.
