What Would Solar Tell Her Younger Self? She Looks Back at 35

K-pop group MAMAMOO member Solar, now 35, is looking back on her 20s through a new single. She will release "To My 20s" (Naui 20daeege), featuring harmonica by singer-songwriter Harim, on Nov. 12 at 6 p.m. KST.

Solar contributed to both the lyrics and composition. The song reflects on the years she spent working tirelessly toward her dreams. Through its lyrics, she delivers a message to her younger self: It's okay to slow down sometimes.

Singer-songwriter Harim contributed harmonica to the track. His performance accompanies Solar's vocals, adding to the song's reflective atmosphere.

The music video will be released alongside the single. It moves between scenes from Solar's 20s and her life today. Footage from her younger years is contrasted with scenes of her walking leisurely through a park, showing how her outlook has changed over time.

Ahead of the release, Solar shared a message through her agency.

"This is a story I want to share with everyone living in a difficult and demanding world," she said. "I hope that while listening to this song, people can take a moment to offer themselves some comfort after working so hard for so long. I want to tell everyone that they've worked incredibly hard and done a great job."
