Controversies
[edit | edit source]Season 1
In 2019, Heart Signal cast member Kang Sung-wook was sentenced to five years in prison for sexually assaulting a woman in August 2017. Fellow cast member Jang Cheon reportedly initially served as Kang's lawyer in the case but resigned after six days.[19] Kang's sentence was reduced to 30 months in prison in 2020.[20]
Season 2
Heart Signal 2 cast member Kim Hyun-woo was arrested for drunk driving in April 2018 while the show was airing.[21]
Season 3
After the cast members of Heart Signal 3 were publicly announced, a woman accused cast member Lee Ga-heun of bullying classmates. Cast member Cheon An-na was also accused of bullying. The show's producers denied the allegations.[22]
While the show was airing, another woman told the media that cast member Kim Kang-yeol had kicked her in the stomach at a nightclub in January 2017. Kim admitted to the incident and apologized on social media.[23]
In May 2023, Yongsan Police Station in Seoul applied for an arrest warrant for Seo Min-jae on charges of violating the Narcotics Control Act. This suspicion was raised when Seo Min-jae made an SNS post revealing that she and her then boyfriend, Nam Tae-hyun, took methamphetamine in August 2022. In September 2022, the police finally collected the hair and urine of Seo Min-jae and Nam Tae-hyun, who were suspected of violating the Narcotics Control Act, and requested an appraisal from the National Institute of Scientific Investigation (NFS).[24]
