Girl group Orange Caramel's member Raina talked about the inside story of how they came to be.

In MBC "Three Wheels" aired today, Reina talked about debuting as the unit group Orange Caramel.

She said, "When we first heard the concept and the song of Orange Caramel, we thought they were kidding."

She continued, "In the beginning, we got a lot of insults and someone even told us not to call ourselves singers."

But other than this, she also talked about how close the members are, to the point they are like real sisters to each other.
