In May 2011, the debut album [BOYFRIEND] presented a new paradigm for boy bands, and the second single [Don't touch my woman] attracted the attention of the music industry as well as the advertising industry with each member's outstanding skills and unique charm. Recognized for their potential to grow as Asian icons, Boyfriend came back on December 8, 2011 with the ambitious third single album <I'll Go>.

This album with the best producer in Korea, Sweetune, is expected to meet the expectations of music fans for new transformation and activities with more complete music and intense performances.

Boyfriend's upgraded music! The second work with “Sweet Tune”!!

The third single album [I'll go], the strongest guaranteed check in the music industry, “Sweetune,” who came out as a supporter of Boyfriend, came together again after the second single [Don't touch my woman].

This single, [I'll go], which the combination of Han Jae-ho and Kim Seung-soo, ambitiously complied with, is a pop dance song with an electronic feel. The melody of the melody, which is more faithful than any other dance music, harmonizes with the pretty lyrics, and Boyfriend's clear image creates a unique sensibility like a transparent watercolor. The unique melody rap is also a point of appreciation of this song.
