Kim Go-eun expresses intimate emotional lines in the new Netflix series "Eun-jung and Sang-yeon." This work deals with the friendship of women who admire and resent each other while growing from their teens to their 40s. The series, which will be released on the 12th, centers on the complex relationship between two friends, Eun-jung and Sang-yeon.

Kim Go-eun plays Eun-jung from her 20s and shares deep emotional exchanges with Park Ji-hyun. In the drama, Eun-jung is a character with a lovable personality. Sang-yeon, Eun-jung's best friend in her teens, is fascinated by Eun-jung's sociability but secretly envies it. On the other hand, Eun-jung envies Sang-yeon's wealthy background. While nurturing a friendship that feels like everything to each other, they swallow their jealousy and grow apart when Sang-yeon moves away. They later reunite at a university club gathering.

Kim Go-eun appears as 21-year-old Eun-jung, expressing caution and delight while portraying the emotional flow of buried jealousy rising. After a certain incident causes their estrangement, the two friends experience an awkward reunion in their 30s. Sang-yeon, now in her 40s, has succeeded as a film producer but is diagnosed with terminal cancer and contacts Eun-jung to accompany her to Switzerland for assisted death. This brings their relationship to a new phase.

Kim Go-eun stated, "I deeply looked into myself in my teens, 20s, 30s, and the upcoming 40s, contemplating how to express the lessons, growth, and changed atmosphere that time has given." Based on her acting skills shown in the past blockbuster film "Pawn," she realistically portrays a character that anyone can empathize with in this work.

Kim Go-eun promises a heavier emotional weight different from the emotional lines shown in her previous works. Rather than focusing on the character's changing appearance by age, she captivates viewers with delicate eye expressions. Her face, captured in long-tempo close-ups, reveals complex emotions of admiration and resentment toward someone. There are also moments where Kim Go-eun's unique smile and unpretentious loveliness shine through.

Kim Go-eun plans to portray the 20-year-old Eun-jung, who gains favor through honesty, and the hardened 40-year-old version who becomes a drama writer. Cultural critic Kim Sung-soo evaluated, "Kim Go-eun naturally digests characters with the desire and will to maintain their agency, gaining empathy." He mentioned that this work explores the emotions tied to long-standing relationships among women, aiming to resolve the past and future, and is expected to receive strong support especially from female viewers.

The chemistry with Park Ji-hyun, meeting for the second time since "Yumi's Cells," also draws attention. Critic Kim said, "Both actors focus on the situation and moment, reacting well to each other," adding, "This work is worth anticipating how Kim Go-eun will respond to the character Sang-yeon and express Eun-jung's emotions."

"Eun-jung and Sang-yeon" is a work that seriously deals with women's friendship, growth, and complex emotional lines, with the chemistry between Kim Go-eun and Park Ji-hyun being highlighted. The series is expected to deeply move viewers.
