I found this in shuutenshi tumblr. I think it's from interview or something, idk.

SECRET's Ideal Types in B.A.P

Hyosung: Jongup. He's kind and dance well.

Sunhwa: YoungJae. Because I did 'Everything Pretty' with him. And he takes care of me.

Zinger: Youngjae. He's totally cute.

Jieun: Bang Yongguk. Because of the visual. He's the visual of B.A.P.

MY JIGGUK/YONGEUN/BANGJI FEELS. And Hyosung's type is somehow unexpected XD
