Huh Gak was also a participant in Plan A Entertainment's "First Episode" release, a duet with A Pink's Eunji titled "Beach". This upcoming "Second Episode" release seems to be hinting at 3 more participants, whose backs are turned in the newly dropped teaser photo.
Suspicions are leaning toward members from Plan A Entertainment's upcoming boy group, said to be A Pink's brother group. They'll be greeting fans through a reality show title 'Me&7Men' starting August 30, before their official debut.
Stay tuned for more info on the upcoming release!
