The sister of Sunwoo Eun Sook accused broadcaster Yoo Young Jae of sexual assault.

According to Pop News, the statements were made during Yoo's trial at Suwon District Court on December 10, at which he faces several sexual crime charges.

In court testimony, the sister, whose first name was not disclosed, described degrading forced molestations that started shortly after she moved in with Yoo and Sunwoo Eun Sook in October 2022.

Describing an incident from March 2023, she said, "I have a habit of holding the dog on the left side, and (Yoo Young Jae) twisted my nipple without a word."

She went further detailing her experiences and alleging that Yoo hugged her from behind in April 2023 and entered her room without permission on several occasions.

"I was yelling at Yoo Young-Jae, saying, 'I'm the executioner; what are you doing?'" she testified.

Sunwoo Eun Sook also testified about a frightening incident that took place while she was away for a day serving as a panelist for a golf event.

She described Yoo, still in just thin silk boxer shorts, following her outside, making lewd comments, and hugging her from behind.

The couple's rocky relationship has been in the news since their wedding in October 2022 and their divorce in April 2024.

Media reports suggest Yoo's hidden common-law marriage was discovered by Sunwoo Eun Sook through media reports after their separation.

A lawyer for Yoo Young Jae has confirmed that he is married to three women but has denied any assertion of a common-law marriage.

The broadcaster finds himself in a number of controversies involving his personal life.

The information shared by Sunwoo Eun Sook and her sister amid testimony in the ongoing trial has stunned many and ignited a deeper conversation regarding the prevalence of sexual assault in the entertainment industry.
