On Mnet's 'Beatles Code 3D,' 4minute talked about the time they all ran off together, leading to some rough consequences but their ultimate formation as a group.

HyunA began, "During our training period, we thought, 'Let's go hang out together.'  Our cell phones were turned off.  We didn't mean to at first, but as we ignored a phone call once, the whole thing got bigger and bigger."

At the time, someone from the agency asked, "Where are you guys?" and worried a lot. In the end, only Jiyoon and Gayoon were kicked out even though the girls had all run off together.  The reason that only those two were thrown out still remains a mystery to the girls.

HyunA and Sohyun continued, "It was very distressing [that only those two members were kicked out].  The rest of the members went on their knees and begged for forgiveness for a week.  Even when the other trainees left for the day, we snuck in at the break of dawn and practiced," which is how they ultimately were formed and debuted as a group.

Could you imagine 4minute without Gayoon or Jiyoon?
