Recently, Lisa Blackpink released an emotional and sweet MV "Dream". It was because of the intimate scenes between Lisa and the male lead Kentaro Sakaguchi that the rumors of the two were stirred up. At the same time, romantic scenes with co-stars also caused Lisa to face malicious comments.

Recently, an article on social network X (formerly Twitter) unexpectedly shared a moment of a TWICE Sana member interacting with Sakaguchi Kentaro backstage at the Prada event at Milan Fashion Week. The author of the post said that the photos of Kentaro and Sana together are even more real than Lisa and Kentaro, as if they were a couple. This post received 9 million views and spread quickly.
Immediately after that, the online community divided into many opposing opinions. Many people expressed their views on defending Lisa and criticized this as a boring comparison. Some believe that Lisa's non-expression was deliberately "taking advantage" of her co-star to create a dating effect. However, the majority thought that dragging Sana into an unrelated incident was united because it would have a negative impact on her.
The lyrics and content of the MV "Dream" reflect the past relationship of a girl, when she still cherished her feelings for her ex-lover. But that affection was not rewarded, because the other person seemed to have moved on. Despite that, the girl still hopes that the two can continue to be friends. Notably, the song clearly shows a time frame of "year 2019", Lisa participated in composing this song, so there were speculations that the female singer was telling her own old love story.
Meanwhile, the identity of Lisa's ex-boyfriend is suspected to be rapper One (or Jaewon) who worked under YG Entertainment. One left YG and disappeared from the entertainment industry after 2019, an important year mentioned in the song "Dream". However, these are just rumors without concrete evidence. Lisa and the management company have not commented on this issue.
