In the art book The Art of Solo Leveling, released on August 27, 2026, creator Chugong identified a significant flaw in his writing of lead character Sung Jinwoo. The author admitted he failed to effectively convey the internal struggle between Jinwoo's humanity and his transformation.
Why it matters
Chugong believes his inability to portray this internal conflict led readers to interpret Jinwoo's personality shift as mere power growth. He cited a lack of resources or time as the reason for this oversight in his original narrative.
The author reflected on the character's arc in The Art of Solo Leveling, which launched on August 27, 2026. The movie Solo Leveling: Beyond the System is currently slated for a theatrical release window between 2027 and 2028.
