Actresses Kim Hee-sun and Song Hye-kyo warmed fans' hearts with their enduring bond.

On September 18, Kim Hee-sun shared on Instagram, "The prettiest, kindest, most lovable and talented Hye-kyo in the world. Thanks to her, the entire cast and staff were truly happy."

The post revealed that Song Hye-kyo had sent a snack and coffee truck to Kim Hee-sun's filming set. Song left a message saying, "Unnie~ stay strong during filming. Love you."

She added a sweet note to the staff: "I'm looking forward to your amazing project. Please enjoy and keep up the great work. And please give lots of love to our Hee-sun unnie." Kim Hee-sun responded with gratitude, writing, "Thank you. Love you."

Kim Hee-sun is currently filming TV Chosun's weekend drama No Next Life (working title), written by Shin I-won and directed by Sung Do-joon. The series follows three women in their forties confronting a "second adolescence."

She plays Jo Na-jung, a former top show host and now a mother of two. Facing career setbacks, she challenges herself to return as a star show host with a million-dollar salary, delivering a heartfelt story of middle-aged women navigating growth and resilience.

No Next Life premieres in November and will also be available for streaming on Netflix.
