Young Mazino in Modern Warfare 4

Young Mazino plays Private Park Hyun-Jun in Call of Duty: Modern Warfare 4. He is the American actor known for Paul Cho in the first season of BEEF and Jesse in HBO’s The Last of Us. His professional name is Young Mazino; his birth name is Christopher Young Kim, and some early screen credits use Christopher Kim.

Park is a young South Korean soldier caught in the invasion at the center of MW4’s campaign. This profile connects that character credit with Mazino’s earlier work, training, and breakout performance without revealing the new campaign’s ending. His television characters and game character are separate roles, even when viewers recognize the same performer.

Private Park Hyun-Jun in MW4

Young Mazino plays Private Park Hyun-Jun.

Park faces live combat for the first time alongside his squad. What starts as a routine patrol descends into the full-scale invasion, forcing him and his unit into a fight through collapsing cities and counteroffensives. His viewpoint places the player close to the pressures of a young soldier on the ground, rather than beginning with the history of a long-established Task Force 141 operator.

Mazino’s character name can be shortened in cast lists and discussions. Park Hyun-Jun is the fuller identification used here, while the spacing “Hyun Jun” does not refer to a different soldier. The shorter “Private Park” keeps the rank and surname but leaves out the given name.

The campaign also follows Captain Price outside the system on a revenge-driven mission. Park’s presence is a separate narrative viewpoint within that wider conflict. It does not make him a new name for Price, Ghost, or another returning character, and the actor credit does not disclose Park’s eventual fate.

Christopher Young Kim and the name Young Mazino

Mazino was born in Maryland and grew up in Silver Spring with Korean immigrant parents. He has two older sisters. His professional name combines his Korean middle name with Mazino, taken from Urek Mazino, a character in the Korean comic Tower of God.

Young Mazino, the actor also known for Paul Cho and Jesse.

He adopted the stage name in 2018, when registering with the Screen Actors Guild. The choice helped distinguish him from the large number of actors sharing the surname Kim. It is therefore useful to search both forms when looking through his early work: Christopher Kim appears in several credits before Young Mazino became the established professional name.

The different names do not identify two performers. Christopher Young Kim is the birth name, Christopher Kim is a shortened early credit, and Young Mazino is the name used for the MW4 performance. Keeping those forms together makes it easier to trace the career without merging him with unrelated actors whose surname is also Kim.

His background includes formal music training, with violin remaining part of his life through college. He also participated in film and theater while growing up. Those activities came before the move to professional acting, rather than beginning as preparation for a particular game role.

Moving to New York and training

Mazino attended the University of Maryland, Baltimore County, but left before completing his degree. He moved to New York City in 2014 to pursue acting and trained at the Stella Adler Studio of Acting for a year. The move followed a decision in his early twenties to take the ambition seriously rather than remain on a more predictable career path.

During that earlier period, he worked as a lifeguard with Ocean City Beach Patrol in Maryland. Responding to a fatal incident made him think about how uncertain life could be and strengthened his decision to attempt an acting career. That experience belongs to his personal path into the profession, not to Private Park’s fictional military background.

The move did not immediately lead to a full-time screen career. He took a series of jobs and later worked for the luxury cosmetics business Fresh, rising to senior business-intelligence analyst over a six-year period. Acting classes and small television parts developed alongside that work.

He eventually chose to leave the corporate role. The pandemic then disrupted the period in which he was trying to pursue acting without that regular job. He spent time away from New York, cycled across the country, and worked on a documentary with friends before the opportunity to audition for BEEF arrived.

Paul Cho and the BEEF breakthrough

Mazino’s breakout role was Paul Cho, Danny Cho’s younger brother in the first season of BEEF. Steven Yeun plays Danny, while Ali Wong plays Amy. The series begins with a road-rage incident between Danny and Amy that expands into a conflict affecting the people around them.

Paul initially appears less interested in the escalating dispute than in video games and escaping the shape of his own life. Mazino recognized parts of himself in the character’s description: a younger brother overshadowed by an older sibling, uncertain work, and a life that had not followed the conventional college-and-career route. That personal connection helped him approach the role.

His performance was not simply a copy of his everyday behavior. He also planned changes in Paul over the season. As the character becomes more confident, Mazino adjusts his posture, using a physical shift alongside the emotional development. That is a concrete example of the work behind a role that may initially seem casual or unforced.

The way Paul speaks was another deliberate choice. Mazino was aware that he could mumble and was concerned about articulating clearly. Series creator Lee Sung Jin felt the less polished delivery suited Paul, who was not meant to sound like an unusually eloquent or outgoing person. The character’s speech and posture therefore worked together as parts of the performance.

Preparing the relationships in BEEF

Before filming, Mazino and Steven Yeun spent time playing basketball together in Pasadena. The activity helped them find the energy of the brothers’ relationship. That preparation offered a physical way to explore the connection between the characters before performing their scenes.

Mazino and Ali Wong also spent time walking on the beach in Venice and talking about family. Their preparation concerned the particular relationship between Paul and Amy, rather than the brothers’ dynamic. These were different ways of building rapport with two co-stars whose characters connect with Paul in different circumstances.

Mazino also approached Paul as a flawed, multifaceted person. The appeal was not to present an idealized character solely as a statement about representation. Paul could be immature, vulnerable, and capable of change within the same performance. That creative aim helps explain why the character’s personal weaknesses remain part of the portrayal.

BEEF’s first season premiered on Netflix in April 2023. Mazino appears as a main cast member across ten episodes, and the performance earned a Primetime Emmy nomination for Outstanding Supporting Actor in a Limited or Anthology Series or Movie. This is a nomination for Paul Cho, rather than an award claim attached to his later MW4 role.

Jesse in HBO’s The Last of Us

Mazino plays Jesse in the second season of HBO’s The Last of Us. The casting was announced in January 2024, and the television performance followed his BEEF breakthrough. For a viewer recognizing him from another game-related production, Jesse is the most relevant later television credit.

The medium matters in this case. This identifies Mazino’s role in HBO’s television adaptation, not a claim that he performed Jesse in the original video game. His Modern Warfare 4 credit, by contrast, is a game performance involving voice and motion capture.

Paul Cho, Jesse, and Private Park Hyun-Jun are three separate characters. Knowing which production contains which role is more precise than describing all three as “the BEEF actor” or assuming that a recognizable face carries the same fictional history between projects.

Earlier film and television credits

These earlier appearances explain why his face may be familiar even before Paul or Jesse comes to mind. Most of the television entries in the table are tied to an individual episode, unlike the ten-episode BEEF role. The exact character name is useful when searching through a large series with many guest performers.

His work also includes an appearance as a love interest in SZA’s 2023 “Snooze” music video. That is a music-video performance, separate from a film, series, or game credit. Together with the earlier Christopher Kim entries, it broadens the ways a viewer may have encountered him before Modern Warfare 4.

For the current game, the identity remains straightforward: Young Mazino is the performer behind Private Park Hyun-Jun. The earlier career explains the recognizable actor; the MW4 character name identifies the young soldier in the new campaign.
