Ha Jung Hoon in Boy, With Caution
Ha Jung Hoon plays Lee Hyeon-jae in the 2026 Korean drama Boy, With Caution.
The Korean title is 소년, 주의. HanCinema lists the series as beginning on September 30, 2026, with Ha Jung Hoon credited as Lee Hyeon-jae.
The series follows Jang Gi U, a 32-year-old temporary high-school teacher whose past became complicated after an inappropriate rumor involving a student. Lee Hyeon-jae is one of the central young characters in the story.
The role has brought Ha considerably more attention because it places him at the center of a contemporary Korean BL drama rather than in the supporting roles associated with his earlier film work.

Lee Hyeon-jae is Ha Jung Hoon’s character in Boy, With Caution.
The character is a 21-year-old student who becomes connected to Jang Gi U, played by Ryu Se-il. The show’s storyline explores the complicated relationship between the characters while dealing with social judgment, rumors and personal boundaries.
For Ha Jung Hoon, the role marks a major step into leading television work.

His modeling career developed during the period when his acting work was less visible, allowing him to remain active in the entertainment and fashion industries.
Ha Jung Hoon Theater Work
Ha has also gained experience in live theater.
His professional profile lists a 2024 production of Almost, Maine, in which he played the characters Jimmy and Phil.

His agency representation reflects the next stage of his career as he moves further into professional acting.
Ha Jung Hoon Girlfriend
There is no reliably confirmed public information about Ha Jung Hoon’s current girlfriend.
Because he stars in a BL drama, fans may naturally be curious about his personal relationships, but his on-screen romantic role does not establish anything about his real-life dating life.
Unless Ha Jung Hoon personally confirms a relationship through a reliable public source, his current relationship status should be described as not publicly confirmed.
Ha Jung Hoon Boyfriend
There is also no reliable public confirmation that Ha Jung Hoon has a boyfriend.
His participation in a BL drama should not be used as evidence of his personal sexual orientation or relationship status. His character and his real-life identity are separate matters.
Ha Jung Hoon Family and Parents
Detailed information about Ha Jung Hoon’s parents, siblings and wider family has not been reliably documented in the major sources reviewed for this biography.
For that reason, specific claims about his parents or family members should not be presented as confirmed facts.
Ha Jung Hoon Net Worth
Ha Jung Hoon’s net worth has not been publicly disclosed through a reliable financial source.
He has worked in acting, modeling, theater and commercial projects, but there is no authoritative public figure establishing his current personal wealth.
Celebrity-net-worth estimates found online should therefore be treated cautiously rather than presented as verified information.
