Yes, Le Sserafim is a K-pop group with five members: Yunjin, Kazuha, Chaewon, Sakura, and Eunchae, and among them, Yunjin is the most fluent in English because she was raised in New York, which makes her a native speaker. Kazuha also speaks English well, thanks to her time studying ballet in England. She has shown excellent pronunciation and can communicate effectively in English, although she might not be as fluent as Yunjin.
Chaewon and Sakura are learning English, but they are not as confident in their speaking skills. Chaewon has good pronunciation and sometimes uses rehearsed lines, while Sakura is improving her conversational skills but still struggles with vocabulary and pronunciation. Eunchae is also learning English, and while she can read and understand some words, she is still developing her speaking abilities.
Overall, while not all members are fluent, they are all working to improve their English skills, especially as they interact more with international fans and participate in global events. This will likely help them become more comfortable speaking English over time.
As Le Sserafim continues to grow in popularity worldwide, their English skills will become increasingly important for communicating with fans and participating in international interviews and performances.
