Wanna.B recently returned with a new single entitled 'Why' and had an interview, where they talked about promoting at the same time as Taeyeon with the same song title.

Ami said, "When we first found out about Taeyeon's song title, we were so taken aback. The word 'Why?' really came out like in our title song.  However, it is such an honor to even be able to come back the same day as a senior whom we've always respected so much.  I personally like the song 'I' so much.  Thanks to her refreshing voice and hopeful lyrics, it's a song that I can listen to happily.  She's an artist with an exclusive charm."

Eunsom added, "I heard that Wonder Girls, whom I've watched over since I was young, is making a comeback.  It's an honor that we get to stand on the same stage.  I'm also happy that we get to be with eminent girl groups.  We will work hard with a fun rather than competitive attitude."

Good luck!
