[E-Daily Starin YUN GI BACK Reporter] The moment actress Han Ga-in appeared, the atmosphere of *Rookie 4: Sabotage* changed instantly. She infused unexpected excitement into the grueling daily lives of soldiers nearing the end of their service, adding new vitality to the drama.

In the seventh episode of the ENA Monday-Tuesday drama *Rookie 4: Sabotage*, which aired on the 14th, Han Ga-in made her full-fledged debut as Jeon Woo-ju, the older sister of Jeon Gye-jeong (played by Kim Dong-jun). Choi Byeong-nam (played by Kim Hee-soo), who had been suffering from post-breakup blues after splitting up with his girlfriend, regained his vitality as if nothing had ever happened after meeting Jeon Woo-ju, and his barracks mates were also instantly captivated by her charm.
In particular, the scene where Jeon Woo-ju—who had been affectionate and composed in front of her fellow soldiers—suddenly changed her demeanor upon seeing her younger brother Jeon Gye-seon drew laughter. Their behavior as a real-life sibling pair—unhesitatingly taking jabs at each other and even getting into a scuffle—created an unexpected twist.
Han Ga-in added a fresh dimension to the show’s military-centric atmosphere with just a brief appearance. She brought out the character’s contrasting tones by switching between a commanding presence that drew all the soldiers’ attention and a warm, approachable side that emerged when she was with her younger brother. Above all, Han Ga-in’s striking resemblance to Kim Dong-jun created chemistry that went beyond that of real siblings.
The episode also featured 2nd Company’s “Operation True Education” targeting the issue of price gouging in the military guard zone. The unit took direct action against unfair business practices targeting soldiers, securing preferential treatment policies for military personnel and mutually beneficial solutions, adding a sense of catharsis to the episode.
Toward the end of the episode, tension mounted as the 2nd Company was deployed as the opposing force in a large-scale “Patriotic Training” exercise, facing off against the Marine Corps.
Viewership ratings continued their upward trend. Episode 7 recorded a 4.6% national rating and a 4.2% rating in the Seoul metropolitan area, with the highest per-minute rating among national households reaching 5.2%. The show also maintained its position as the No. 1 Monday-Tuesday drama and the top-rated program in its time slot.
Episode 8 of “Rookie 4: Sabotage,” which has taken on a new vibe with Han Ga-in’s加入, will air on ENA at 10 p.m. on the 15th. It is also available on KT Genie TV and TVING.
