Fans notice every little thing about their idol, so it is no surprise that many fans began to notice these idols do cute yet strange things with their hands! It's called a 'congenital mirror movement' where when you make a gesture with one hand, the other hand involuntarily mirrors that movement! Most of us have it as a baby and grow out of it eventually, but not these adorable idols! It is a very real disorder but nothing serious! Of course, we think even this odd genetic disorder is absolutely adorable.
