A 12 years old girl that doesn't act at her age, receiving training by BTS personally. That makes her become "THE GIRL THAT THE COMPANY BROKE THE 'NO GIRL TRAINEE' RULE" because of how talented she is. Being the only girl, BTS make her live with them. They thought that it would be hard to take care of a 12 years old, but who know if it is them taking care of her or her taking care of them.... Starting : 24 Feb 2022.
