A seven member girl group 7size has completed its selection of new members and will be looking ahead to a comeback with a new single soon. They had debuted in 2009 as the first trot group in the country but didn't really go anywhere in terms of their career as artists. They will however release their second single album in May titled, Thank You. They've been practicing dancing and singing for over ten hours each day and will be hoping for more success this time. TGN Entertainment said, "This new album is more geared towards pop, dance, modern and more instead of trot. We will show everyone a true girl group." They're also looking to target variety shows so I guess we'll be seeing a lot of these girls starting this May.
