Berry Good's Sehyung is edgy in white as the next member of the Heart Heart unit

As previously reported, Heart Heart consists of Taeha, Sehyung, and Gowoon, and is a Berry Good unit team with a different, more mature mood than the original 6-member team. 

The unit's debut single "A big mess, a big mess has happened" (literal translation) will be out on April 27 at 6PM KST.
