Han Groo's father is a TV
commercial director and her mother used to be a professional
model, which made her familiar with and naturally drawn to show business from a very early age. Upon her return to Korea, the aspiring actress signed with the management agency Climix Academy. But at her agency's suggestion, she launched a singing career in 2011 with the
EP GROO ONE, followed by the
single My Boy. She was nominated as Best New Female Artist at the
2011 Mnet Asian Music Awards. Han Groo later admitted that acting was her real passion from the beginning, but she had wanted to grab whatever opportunities available to her. However, she found it difficult to stand out as a singer given the huge level of competition in Korea's music industry, especially among
girl groups riding the coattails of the
K-pop revolution. She then joined her first network series, the
MBC daily drama
Just Like Today, saying that when she read the script, she felt instantly attached because of the character's similarities to her real-life personality, someone "who's bright and positive despite her difficult situation." In June 2022, Han signed with SBD Entertainment, prefiguring a potential comeback in the entertainment industry after seven years away. ==Personal life==
