ZE:A's members Hwang Kwanghee and Im Shiwan revealed their friendship.

Yesterday, Kwanghee posted on his Twitter, "My friend who is close to me. His name is Im Shiwan. He has thick lips and his face is just a little bit better looking than mine. He's close to me! We're close. Even though Shiwan is making that face he cares for me. My grateful friend Shiwan" along with a picture.

In the picture, Kwanghee is smiling brightly, but Im Shiwan is pouting his lips, making an angry look. Even though their faces represent opposite feelings, their close friendship could be seen in the picture.
