Controversies
[edit]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.[24] Kang's sentence was reduced to 30 months in prison in 2020.[25]
Season 2
Heart Signal 2 cast member Kim Hyun-woo was arrested for drunk driving in April 2018 while the show was airing.[26]
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.[27]
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.[28]
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).[29]
Season 4
In June 2026, a series of private Instagram stories of Kim Ji-min was leaked which included political comments, using derogatory expression against her mother, display of her boyfriend's gifts, and slandering comments against Single's Inferno 5's Park Hee-sun. She later posted an apology letter and announced legal actions.[30]
Season 5
In June 2026, an anonymous netizen claimed in a post that Jeong Gyu-ri is having an affair with a married man whose wife had recently given birth. An alleged photo of the two kissing in an elevator was included in the post.[31]
