BLACKPINK’s Jennie took the stage at Inspire Arena in Seoul on March 14, 2025, for her solo Ruby Experience concert. Fans took to social media when they discovered that Chahee, a former idol, and allegedly Jennie’s longtime friend attended the concert. Her appearance gained attention due to speculations that the idol's song Twin from her solo album Ruby was inspired by their friendship.
Since its release, Twin has been a topic of discussion among fans. Many believed it reflected the end of a deep friendship. The song’s lyrics hinted at a close bond that drifted apart over time, and it described a long-lasting connection and a hope for future reconciliation.
While Jennie never confirmed the inspiration behind the song, Chahee's presence at the concert sparked further discussion. She shared a story on Instagram featuring a photo from the event with a red heart emoji.
Adding to the speculation, some fans pointed out that when she sings "twin," it sounds like "swim," which directly translates to "Sooyoung" in Korean—Chahee’s real name.
During her past performances of Twin, the Solo singer often appeared emotional while singing the song. This time, with Chahee in the audience, many fans speculated that her emotions might have been even more intense. An X user, @Kwooluvsu wrote,
"She HAD to have cried. I’ve never experience a friendship breakup like that, but when I heard the song live, I teared up."
