The upcoming film 18 Youth has unveiled its first official poster featuring Jun So Min and Kim Doyeon, offering an early glimpse into the emotional dynamic at the heart of the story. On March 4, production company 26 Company confirmed that 18 Youth will premiere on March 25, alongside the release of a main poster highlighting the teacher-student relationship central to the narrative.
Based on a novel, 18 Youth tells the story of Hee Joo, played by Jun So Min, a high school teacher known for her unconventional educational philosophy. While she enjoys popularity among her students, she faces criticism from fellow faculty members for her unorthodox methods. Opposite her is Soon Jung, portrayed by Kim Doyeon, an 18-year-old student who initially finds her eccentric homeroom teacher more irritating than inspiring. WJSN’s Chu So Jung (Exy) also appears in 18 Youth as Kyung Hee, the top-ranking student in Hee Joo’s class.
The newly released poster captures Hee Joo and Soon Jung standing side by side under warm sunlight, exchanging relaxed smiles that suggest a gradual shift from tension to understanding. The accompanying tagline, “I met a teacher who teaches possibilities instead of just the right answers,” hints at the transformative impact their relationship will have on both characters. In 18 Youth, this evolving bond unfolds at a stage of life often marked by uncertainty and the impulse to escape.
As the story progresses, Hee Joo emerges as a teacher who seeks to connect with her students emotionally before academically, while Soon Jung wrestles with a heartfelt yet awkward dream of traveling to Africa after graduation. Through their interactions, 18 Youth portrays moments of vulnerability, growth, and mutual recognition. The relationship between Hee Joo and Soon Jung becomes a defining milestone in the young student’s journey, promising audiences a narrative filled with warmth and reflection.
With its theatrical release set for March 25, 18 Youth places Jun So Min and Kim Doyeon at the center of a story about youth, possibility, and the subtle yet profound influence of mentorship.
