In addition to brief teaser clips of Seo UnSeo Jun, Seungjae, Ro Hee, and SuAh, SeolAh,Daebak, there was a clip of a new child, by the name of Lee Joon!
The teaser showed a never-before-seen home, with a baby boy just woken up in a tent in the living room! His name is Lee Joon, and while we see brief glimpses of his mother's face (she seems to be a non-celebrity), his father's face has been blurred out.
