BTS never thought the day would come that a young girl would join their group but their company thought she would bring a touch of innocence to the tough image they were portraying after their debut. Kim Sujin, or Sun as she's famously known as, is a talented rapper and vocalist as well as an accomplished dancer. She may have came in late to the group but there's no denying how much the boys have grown to love and care for their female maknae. Especially the other maknae.
