"
Why Are You Being Like This?" was released as the
lead single for
Temptastic on November 23, 2010. The single is the group's first release to feature their newly added seventh member,
Hwayoung. Written by label-mate
Yangpa and produced by Kim Do-hoon and Lee Sang-ho, the song contains influences from
1980s synthpop and features the use of an electric guitar in the instrumental. The music video for "Wae Ireoni" premiered on November 23, 2010, the same day as the single's release. "Yayaya", the EP's second single, was released alongside its parent album on December 1, 2010. In a statement regarding the abstract lyrics,
E-Tribe explained: "I used the hook technique to turn the song into a sort of riddle. I wanted the unique expressions to arouse the curiosity of listeners. [...] I wanted to express the unique music through lyrics that sounded like a spell. Please don’t misunderstand it and just enjoy the exciting music." The music video features costumes and gestures (patting their hands over their mouths, finding a young man (
No Min-woo) who crashed there and tying him to a stake, and living in teepees) some have called stereotypical Native American. On the December 12, 2010 broadcast of
Mnet's
M! Countdown, "Yayaya" won the first place spot. The song was eventually re-recorded in Japanese and released on November 30, 2011, serving as the group's second single in the territory. ==Promotions==
