Gong Seung-Yeon, known for her role in the drama 'Perfect Crown,' opened up about her feelings regarding her younger sister Jeongyeon's success as a member of the K-pop group TWICE during a recent episode of the variety show 'You Quiz on the Block.' While she expressed genuine happiness for Jeongyeon, Gong admitted to feeling inadequate and envious at times, particularly as she faced her own challenges in the entertainment industry. After gaining initial fame from the 2015 drama 'Heard It Through the Grapevine,' opportunities dwindled for Gong, leading to significant financial struggles that forced her to move back in with her parents. She described the emotional toll of feeling like she was falling behind her sister, who has become a global star. Despite these feelings, Gong Seung-Yeon remains determined to carve out her own path and has been actively seeking auditions to prove herself. Today, both sisters are thriving in their careers, with Jeongyeon shining in K-pop and Gong Seung-Yeon steadily building her acting portfolio.
