The glamorous world of K-dramas may conceal some back-stage struggles, where some K-dramas actors have earned their place in infamy for their difficult attitudes and actions against production staff and actors as well as media personnel.

Here are seven K-dramas actors and actresses who have been under scrutiny for their behavior while on set:

1. Seo Ye-ji

Known for roles in "It's Okay to Not Be Okay," Seo Ye-ji has been accused of creating a hostile work environment through verbal abuse, intimidation, and cussing at staff for minor mistakes. Former employees reported constant fear, phone checks to prevent recordings, and restrictions like not eating when she was in a bad mood. She also allegedly manipulated ex-boyfriend Kim Jung-hyun's behavior on the set of "Time," instructing him to be rude and demand script changes.

2. Kim Jung-hyun

During the filming of "Time," Kim Jung-hyun exhibited cold and distant behavior, refusing skinship scenes, avoiding eye contact with co-star Seohyun, throwing tantrums, and demanding script rewrites that led to 13 missing scenes. His attitude extended to the whole cast, and he ran away from set if things didn't go his way, later apologizing in a handwritten letter attributing some actions to personal influences.

3. Jisoo

On a three-month filming set, Jisoo allegedly displayed a terrible attitude by not greeting anyone, smoking and discarding cigarettes carelessly, and treating his manager like a servant with poor manners and orders. Former staff described him as a "scumbag" due to this disrespectful conduct.

4. Bae Suzy

Rumored to be late to photo shoots, annoyed when resuming filming after breaks, and using profanity not fitting for her idol image, Bae Suzy has been called the rudest among girl group members in speculations from a 2013 media report. She was also accused of running off set and showing reluctance to film.

5. Ma Dong-seok

Frequently criticized for no-shows at press interviews and promotional events for films like "The Roundup," Ma Dong-seok has been named the rudest Korean actor in surveys, placing unfair burdens on co-stars and crew. He often cites personal reasons without transparency, leading to resentment among reporters.

6. Kim Tae-ri

Ranked high in rude behavior surveys, Kim Tae-ri has been accused of being dismissive and inattentive during interviews, acting immaturely with a superiority complex, and disregarding professional obligations. Insiders report unprofessional conduct on set, including rumors of trash-talking a director and admitting to stealing a film director's watch.

7. Nam Joo-hyuk

Nam Joo-hyuk made a perceived rude remark to co-star Bae Suzy after a kiss scene in "Start-Up," jokingly asking if her lunch smelled like Samhap, implying bad breath tied to her hometown. Combined with bullying accusations and reckless behavior affecting promotions, this has led to frustration among staff and reporters.
