Mostly haehyuk.

• SLHusky My favorite smutty unnie! You should check and read all the fanfics she's write, it's amazing and fantastic! Always have mysterious vibe and each plot and development that will makes you curious and wants to read more and more. Bonus point, she writes her stories in a good (a very good one) grammar. Another bonus, the bed scene is very very good! Perfect for our perverted mind.
