The question of who was rejected in Blackpink is misleading; rather, the more accurate interpretation revolves around contract renewals. Specifically, reports indicate that Lisa of Blackpink rejected an initial contract renewal offer from YG Entertainment in September 2023.
While the term "rejected" is often used, it's crucial to understand the context. It doesn't imply Lisa was rejected from Blackpink but instead turned down an offer to renew her individual contract with the agency responsible for managing Blackpink. This situation sparked considerable media attention and affected YG Entertainment's stock price.
Therefore, the closest answer to the initial question is Lisa, in terms of rejecting a contract renewal offer. It's vital to clarify that this doesn't signify her departure from the group itself, although the situation remains fluid and open to future developments and negotiations.
