In order to find out the truth behind the friend's words, the MCs brought out a lie detecting machine.  Before the official test, they decided to try it out on SinB, asking her, "You're the prettiest in G-Friend?" to which she denied with, "Nope."  I wonder who she thinks is the prettiest then!

The results of the test showed that she was telling the truth to which Shin Dong Yup said, "This is also sad," making everyone laugh.  The follow-up question was, "You're the best at dancing?" and she replied this time affirmatively with, "Yes."

Do you think she's the prettiest and/or the best dancer of the group?
