“Gives me the biggest ick"— Single's Inferno 4 contestant Kim Jeong-su draws viewer backlash for his alleged “red-flag” behavior

Episodes 5 and 6 of Single's Inferno Season 4, released on January 21, 2025, have sparked discussions online, with contestant Kim Jeong-Su facing backlash for what viewers perceive as problematic behavior. Many fans criticized his actions and comments, calling them manipulative and insincere.

While Jeong-Su initially won hearts with his charm and self-described “golden retriever-like” personality, his recent interactions have left audiences questioning his intentions. Jeong-Su’s handling of his connections on the show has particularly drawn ire.

For those unaware, Single's Inferno 4 contestant Kim Jeong-Su is a 33-year-old entrepreneur, who runs multiple cafes and bakeries in South Korea.

Several viewers of Single's Inferno 4 took to social media, labeling his approach as “red-flag behavior,” likening it to the actions of a past contestant known for disrespectful conduct. An X user, @maithesis wrote,

"this mofo gives me the biggest ick."

His actions have been described as calculated, leading many to believe he is prioritizing strategy over genuine relationships.

"Jeongsu surely is coping Gwanhee's format but failing miserably. At this point, he is straight up lying to the women. He is aiming to pull a Gwanhee at the end, I can see it. But at what cost? Such a red flag he is," an X user wrote.

"But I really get frustrated with how Sian is always going back to Jeong Su... Like girl, bffr??? He's a total walking red flag!," a fan mentioned.

"Jeongsu is the biggest red flag of this season. There i said it. Since ep2, i already felt that kind of vibe from him. He doesn't seem so honest plus he's like Gwanhee giving girls false hope so he can have more options," a netizen added.

"jeongsu is kinda scary (?) i mean he’s like a casanova in disguise. he knows the game well," a fan wrote.

In one notable moment of Single's Inferno 4, he reassured Lee Si-An about his interest in her, claiming he wanted to avoid pressuring her. However, his subsequent decisions and words left fans speculating about his sincerity, with some calling him a “player” and accusing him of giving mixed signals to multiple participants.

"“he’s no ordinary guy” - lee dahee on jeongsu istg jeongsu will cause a lot of headaches in the future haha he is such a player!," another person wrote.

"I HATE THAT JEONGSU GUY !! he is playing double games. Why is no one talking about that?????," an X user commented.

"nahh forget what i said earlier, jeongsu is weirder than taehwan. i enjoyed the love triangle drama but not anymore. he just likes confusing people. "you're my first choice" and then picks youjin just to avoid burdening sian it's sooo mehh," a netizen added.
