Somehow, the outrage over these allegations spilled over to target Jisoo, with many theorizing whether she was aware of her brother’s actions. The alleged victim then made a post asking the public not to direct any criticism against Kim’s family.

The account has now made two separate posts, talking directly about Jisoo. They explained that the BLACKPINK member may not have known what was going on, and even claimed that they had no idea that Jisoo was Kim’s biological sister until recently.

His sister probably didn’t know. I didn’t even know who she was either. People kept saying they looked familiar, so I looked her up…and only found out after checking Namu Wiki. So, please don’t criticize her.

The account then posted a handwritten letter, further claiming that they didn’t know Kim was related to Jisoo when they got married.

I met him without having any idea that he was his brother. It was only after we registered our marriage and his second daughter kept saying that I looked like ‘XX’ aunt that I looked her up online and discovered the truth.
— The victim’s written statement
This explanation offered Jisoo some much-needed relief from the relentless theories about her complicity in her brother’s alleged abuse. However, all these claims remain one-sided at this point. Despite the big fuss, neither Jisoo nor her agency has yet issued any official statement.
