As BLACKPINK member and actress Jisoo faces fresh family-related controversy, a shocking claim alleges she effectively severed ties with her older brother over a year ago.
Reporter-turned-YouTuber Lee Jin-ho claimed on his channel that "as of May 2025, Jisoo has cut off contact with her older brother." At the time, a whistleblower post surfaced online accusing her brother, referred to as A, of illegal filming, and trust within the family reportedly collapsed afterward. Lee asserted that "it is known the cutoff extended not only to Jisoo but essentially to the entire family as well."
Following the controversy, A is said to have changed his phone number and virtually cut contact with people around him. Because of this, some argue Jisoo was in no position to know about or intervene in later personal-life allegations tied to him.
Rumors that Jisoo was involved in establishing her agency BLISSO were also refuted. In the video, Lee explained, "While A may have provided limited, family-level help at some point, he did not participate in company management nor receive salary or shares in any official capacity." He added that A's name does not appear among key executives on the official corporate registry.
The clearest sign of Jisoo's stance, according to the report, was the Netflix original Boyfriend on Demand end-credit correction. When the project was released, A's name appearing in the credits sparked backlash, but it was explained as a holdover from materials temporarily used during filming. After release, Jisoo learned of the issue, raised strong objections, and—according to the claim—even shouldered costs to request his name be removed.
Jisoo's side has stated through legal counsel that they will respond firmly to false claims linking family matters to the artist. They also clarified they are not providing the individual with financial or legal support and have no plans to do so moving forward.
