In the Netflix series released on March 6, he plays Seo Eun-ho, the campus it-boy inside a virtual dating subscription service. The star brings a fresh, youthful romance to the screen. His ideal “senior” vibe drives the show’s romantic mood and cements his status as a true “wannabe boyfriend.”
Seo Eun-ho’s first entrance―under drifting cherry blossoms―immediately stands out. His warm visuals and soft aura make a lasting impression. After greeting Seo Mirae (played by JISOO) with a bright smile, he adds heart-fluttering moments with thoughtful gestures. Even ordinary campus life transforms into scenes drenched in First Love feels, amping up the romance.
Seo Kang-jun heightens Seo Eun-ho’s charm with tender eyes, a sweet smile, and a low, gentle voice. His delicate emotional beats―and his switch between calm warmth and relaxed ease―bring out the best of a youth romance, hitting fans’ relationship daydreams right on target.
His chemistry with Seo Mirae also cranks up the swoon factor. At first he seems a bit curt, but he gradually reveals a kind, considerate side. That natural shift fills in the character’s emotional arc with detail. With “chemistry master” timing, he keeps the story flowing and makes the romance even more fun to watch.
Through this project, Seo Kang-jun showcases every possible flutter point of his character―delivering a textbook First Love romance. His versatile performance enriches each scene and boosts the overall mood. Expectations are now high for what “Seo Kang-jun-style” romance brings next.
Last year in the drama ‘Undercover High School,’ he played Jeong Hae-seong, a National Intelligence Service agent who goes undercover at a high school, leaving a strong impression as he moved between agent and student. Spanning action, comedy, human drama, thriller, and romance, he led the project with commanding presence. Recognized for that run, he took home the Grand Prize at the 2025 MBC Drama Awards, proving both acting chops and buzz. All eyes are on Seo Kang-jun’s next move.
Meanwhile, ‘Boyfriend on Demand,’ featuring Seo Kang-jun’s rosy-hued romance, runs 10 episodes and dropped in full on Netflix on March 6.
