To promote her solo album Ruby released on March 7, Jennie (Blackpink) announced a series of concerts called The Ruby Experience in 3 cities Los Angeles (7.3), New York (3.10) and Seoul (3.15).
At the The Ruby Experience event in Los Angeles (USA), when singing the song Twin, Jennie was very moved and kept crying. This moment was shared by many fans on social networks.
In a conversation with Apple Music before the album's release, host Zane Lowe said when he heard "Twin" that this is a song that contains very personal emotions, to the point that it can only be based on a real story.
The song is definitely about someone. It was a letter, Zane told Jennie.
Jennie was surprised by Zane's perfect analysis of Twin and admitted, Youve seen through me.

The singer shared that this song is very special and personal to her, but she still decided to release it in the hope that someone could sympathize with this feeling. In addition, Jennie also said that "Twin" helped her end her past relationship.
Jennie's sharing made many viewers speculate that she might have written the song to talk about her ex-boyfriend and the ended relationship. The most mentioned person is V (BTS) - Jennie's most recent rumored boyfriend.
But when Twin was released, netizens realized that the female singer wrote this song for an old best friend. Jennie's fans thought that friend was her former idol Chahee.


On stage in Los Angeles, Jennie cried while performing the lyrics: "We have been together for 10 years/Young, foolish and innocent, my friend/But I know that we are both wrong.
I've never left you, I still see you/When I listen to Ashanti's music on this beach/I don't hug you anymore, but I still remember very well/ Then we will heal, will fix everything when we get older, my friend.
My/ Your/My/You and I, we are far apart/ Like white clouds drifting in the starry sky....

Chahee (former member of Melody Day) was once known as Jennie's close friend, they had known each other before debuting in two girl groups. There were even suspicions that the two established a fashion brand together in 2020.
But in recent years, the two seem to no longer be together as before, no longer having interactions on social networks.
