SISTAR's Hyorin appeared on KBS 2TV's 'Happy Together 3' while preparing for her solo debut.

On this episode, she revealed that she was quite the germaphobe so even if she made a mess, she would clean it up right away.  This caused the other guests on the show to ask which SISTAR member was the messiest in the dorm.

DJ DOC's Kim Chang Ryul stated, "I feel like Bora might be a bit like that."

Hyorin responded, "Whenever I go on talk shows, I always want to talk about my members' private lives, but as they're women, they get a bit sulky," whereas she explained she did not bear grudges and would just ignore anyone bothering her.  

She also said in relation to her being a germaphobe, "If I wear clothes once, I have to wash them and if they are clothes I need to wear tomorrow, they must have been washed.  It's the same with towels. After a certain point, I realized that I was the only one doing the laundry in the dorm."
