Seo Hyun-woo (born 20 November 1983) is a South Korean actor who began his career on stage and made his debut in a musical in 2010. In the same year, he won an acting award at The 9th Off Daehakro Festival.
Seo faced a period of obscurity that lasted for five years following his graduation. Seo naturally turned his attention to Daehakro plays and independent films. He starred as the main lead in Hyung Seul-woo's film Allergy (2015) that received the grand prize at the Fukuoka Independent Film Festival. He also starred in Shin Dong-young's short film Hatred, which received an official invitation to the 70th Cannes Film Festival.

## Early life and education

Seo Hyun-woo was born in Busan on 20 November 1983. He attended elementary and middle school in Tongyeong. Seo later moved to Gongju, South Chungcheong Province, attending boarding school Hanil High School [ko], recognized as a prestigious high school for talented students. Alums include actors Park Jeong-min and Cho Hyun-chul.
During high school, Seo was known for his lively personality and held positions as both class president and vice president. However, the immense academic pressure he faced caused him to lose interest in his studies, leaving him feeling adrift. At the end of his first year, he went to the School Festival and saw a play for the first time. His literature teacher wrote the play. Watching his classmates and older students perform on stage was a memorable experience for him. As a result, in his second year, he decided to join a theater class, which helped him better manage his emotions despite his quick temper. However, he chose to keep his passion for acting a secret from his parents and lacked the courage to pursue it as a career.
He enrolled in the English literature department at Kookmin University, believing that excelling in English was important. However, he soon realized that many of his classmates had more experience living in English-speaking countries, and he felt this path wasn't right for him. In his early twenties, feeling lost and facing challenges, the impending military service intensified his sense of helplessness. Around the age of 20, after completing his first year, he took a hiatus and worked as a bartender in Daehak-ro. It was during this time that he encountered the theater scene and his desire to become an actor began to grow.
   "Every night, theater people from Daehak-ro came to the bar where I worked. They were like uncle figures, but they engaged in serious discussions every night. They recited lines from Greek tragedies like Sophocles and Aeschylus, and they pondered if Hamlet felt this way or if Othello's anger was like this. I secretly observed them every night. I'm not sure if this expression is appropriate, but it was like 'adults playing make-believe.' It was cool. And I was curious about what made them so obsessed. It was from this time that I made up my mind to become a real actor."
During a phone call with his high school literature teacher, Seo revealed that he had taken a break. Despite being seven years older, the teacher listened attentively to his concerns. During the conversation, Seo reminisced about his high school theater class, and the teacher mentioned studying acting at the Graduate School of Korea National University of Arts. The teacher suggested Seo take the entrance exam for his school. Inspired, Seo decided to drop out of college that day.
However, Seo's decision to pursue acting caused turmoil within his family. In 2003, undeterred, he enrolled in an acting academy but left after a month due to its ineffectiveness. Despite paying a monthly tuition of 850,000 won, attending a class three times a week with over 50 students proved inconvenient as he had to wait for his turn. Seo briefly considered private lessons but ultimately decided to study independently. He regularly visited a nearby video store close to his residence at Kookmin University, renting three films per day. With dedication, he would imitate the acting styles of his admired actors. Whenever he encountered challenges, he turned to professional books for guidance. His relentless efforts paid off, resulting in his successful passing of the test.
He was accepted into the Theater Department at Korea National University of Arts. Despite being a couple of years older than his peers, he was unfazed by the age difference. His unwavering determination and perseverance set him apart. Notably, he received a full scholarship for every semester, except the first one.

Both Kim Eui-seok's After My Death and Lee Kwang-guk's A Tiger in Winter received invitations to the prestigious 22nd Busan International Film Festival held in October.
   "Independent films are relatively disadvantaged compared to commercial films, but that's why they seem more interesting to me. The passion to learn and the desire to grow through work are great. Playing the lead role in an independent film allows me to experience a long breath and experiment with myself. This year, After My Death and A Tiger in Winter were invited to the Busan International Film Festival, and personally, I think it will be a very meaningful year."
Further solidifying his presence in the industry, Seo played a significant role as the lover of a North Korean defector with a compelling backstory (played by Lee Na-young) in the opening film of the 23rd Busan International Film Festival.

In the same year, Seo showcased his versatility through notable roles such as Secretary Oh in Son Jae-gon's film Secret Zoo. He strengthened his presence in the public eye through the film The Man Standing Next.

Seo also got his first lead role in tvN drama Flower of Evil. The drama was written by Yoo Jeong-hee, directed by Kim Cheol-gyu, and produced by Studio Dragon and Monster Union. Seo Hyun-woo played the character Kim Moo-jin, a reporter who was obsessed with finding scoop. Kim was a carefree, self-centered, and sometimes cunning person.

However, things got complicated when Do Hyun-soo (Lee Joon-gi) someone who had caused him past trauma, showed up. Kim also had a special romantic relationship with Do Hyun-soo's older sister, Do Hae-soo (Jang Hee-jin).
   "It was my first lead role, so I felt pressured, but I was able to take on the role in an interesting way because it changes like a chameleon depending on the situation. I was really moved when I first started receiving calls after auditioning non-stop. I had really mixed emotions. It's my first time doing a melodrama, and it's my first time acting with someone my age. Even in my 20s, I mainly played roles older than my age, such as teacher rather than student, but everything was new to me. I got to discover new sides of myself while playing roles of people my age."
In 2021, Seo joined a concept performance live dubbing show, Exotic Garden, a combination of film screening with musical theater, directed by Jeon Gye-soo. Love with an Alien [ko] or An Exotic Garden, produced in 1957, was Korea's first color film and the first Korean-Hong Kong collaboration film directed by Jeon Chang-keun, Tu Kuang-chi, and Wakasugi Mitsuo. In 2013, the film was discovered in a Shaw Brothers warehouse in Hong Kong, but the gorgeous natural colors had lost their luster and the sound was lost. Upon returning to Korea, the film underwent extensive remastering and was restored close to the original, but the sound was never found. Fortunately, a script with recorded lines was found. The show recreated the film by adding imagination and includes on-site dubbing by actors and the insertion of vivid sound effects by Foley artists.

Seo landed the role after auditioning, when he had lost a significant amount of weight. After the audition, the director expressed admiration for Seo's performance but mentioned disappointment regarding his lack of an intimidating physical presence. However, the director still desired to collaborate with him, so Seo dedicated himself to gaining weight for the role. In recognition of his portrayal, he was honored with the New Male Actor of the Year award in the film category at the 21st Director's Cut Awards.

Seo felt like he wanted to expand his horizons as an actor, he wanted to try the genre of comedy someday. Later, director Jang Yu-jeong sent him the scenario for Honest Candidate 2. Up until then, He was very excited. But when He actually saw the scenario, Cho Tae-joo seemed difficult.
