LABOUM Solbin Apologized For Speaking Informally!

LABOUM's Solbin apologized for her mistake!

She said 'I was thoughtless'! The incident happened last week on Music Bank when BTS' Jin opened the door of her backstage room and greeted her. She then replied with 'yah Kim Suk Jin'. Some fans bashed her for speaking informally to Jin.
