On January 15, 'Shower Later' made notable music chart rankings as soon as it was released. It has been in the lead on music sites MelOn, Mnet, Naver Music, and Daum Music.

However, 4minute's new single 'Only Gained Weight' released on January 20 made the lead on Bugs, Olleh Music, Soribada, and Genie. The Part 2 album commemorates the group's tenth year anniversary and includes 4minute's unique and truthful voice and qualities. The album is about the broken heart of a woman longing for her ex-lover.

4minute's new song 'Only Gained Weight' is the second collaboration with production team Brave Brothers after the song 'What Is Your Name?' The music chart rankings nodded to other songs such as Girl's Day's 'Something', MC the Max's 'The Wind That Blows', and Ailee's 'Singing Got Better'.
