Gaeun, the leader of HRT Berry, was born in a country where a civil war had been in progress for two decades. When she was getting used to a life of risking it all just for a piece of bread, she received help from an unknown savior -Teacher- and came out into the world. She threw other members in panic by not saying a single word during their first stream, but Choi Ina advised her to smile to the camera while thinking of her Teacher. Her bright smile caused thousands of fans to fall for her.
