15-year-old Zelo, who is currently part of a unit with Yong Gook Bang, is receiving lots of attention.

Zelo appeared out of no where last December 4th on SBS TV's "Popular Song" with Yong Gook Bang performing 'Never Give Up'.

Zelo, in the picture released on December 6th, is showing off his white skin and blonde baby perm hair. Yong Gook Bang is lying down next to him with his thumb in the air and Zelo is turning on his charm.

Yong Gook Bang is playing with Zelo's hair as if he is so cute; they show off smiles as though they get along like brothers. Fans nickname Zelo as 'MarshZelo' showing him affection. 'MarshZelo' comes from the idea that Zelo has skin as soft and white as Marshmallow.

Zelo, who is only 15 years old, surprised staff and fans with his 182cm height, handsome looks, and powerful performance although it was his first.

Zelo and Yong Gook Bang will debut as part of a male idol group early next year.
