Goo dated hairdresser Choi Jong Bum after the two first met on the set of the beauty TV program "My Mad Beauty Diary". On September 13, 2018, Choi broke into Goo’s house drunk while she was sleeping and started an argument that escalated into a violent assault when he allegedly tried to break up with her. Goo claimed that the incident was two-sided, leading both parties to post images of their injuries to the internet to explain their side of the story. During the incident, Goo suffered from uterus and vagina hemorrhage and was also diagnosed with "cervical sprain", "facial contusions and sprain", "lower leg contusions and sprain", and "right forearm and additional sprains." Goo filed a lawsuit against Choi for threatening to release a sex video filmed without her consent in an attempt by him to end her career, and the sex video was submitted to the court per the judge’s request, where it was confirmed privately by him.
During the first trial, Choi denied most charges but admitted that he was responsible only for the destruction of property. On May 26, 2019, Goo attempted suicide in her apartment and was immediately taken to hospital, after which she apologized for worrying her fans. In August 2019, he was acquitted of the charge of filming the sex video without permission as the court agreed that the filming was done without her consent, but because she remained in the relationship they found him not guilty of illicit filming. However, he was sentenced to one year and six months in prison, suspended for three years of probation after being convicted of threatening to upload the sex video, coercing, physically assaulting, and destroying Goo’s property. After news of her sex video went public, Goo was harassed online on social media, despite being a victim of a crime. Upon closure of an appeal to the suspended sentence on July 2, 2020, Choi was sentenced to a year in prison.
