Entertainment Relay recently visited the girls on the set of their “Visual Dreams” MV and gathered some interesting tidbits about the girl.
Evidentally, the members think Soo Young is the smartest member. However, when she took an IQ test on her phone, it told her that she had an IQ of 62. Fortunately for her self esteem, there was something wrong with the app (But how smart do you have to be to figure that out?).

As for the strangest member, Seohyun wins that honor. I don’t quite see it myself but according to Taeyeon, she has a very unique charm.
