Solo Leveling is one of the most popular anime right now, and that’s undeniable. Over the past two years, with just 25 episodes, Solo Leveling has completely dominated the anime scene and is sure to grow even bigger.
Although Solo Leveling is a high-quality adaptation by A-1 Pictures that elevates the manhwa’s battle scenes, it isn’t entirely faithful to the original. The creators made several changes, especially focusing on the character Sung Jinwoo. The anime version of Jinwoo has been criticized for being too cold and lacking expression. Interestingly, Jinwoo in the webtoon is quite different: he’s more energetic and emotionally expressive, surprising readers.
Sung Jinwoo Shows a Wide Range of Expressions in the Manhwa

One of the biggest differences between Sung Jinwoo in the anime and the manhwa is the absence of many humorous and lighthearted moments in the anime. In the original manhwa, Jinwoo has plenty of funny scenes that fans love. His character isn’t just about leveling up, getting stronger, and looking cool. There’s more to Jinwoo, which is why the manhwa portrays him as a much more emotionally expressive character.
Whether blushing, acting silly, or making funny chibi faces, Jinwoo shows it all in the manhwa. When combined with his cold, sometimes ruthless, and incredibly powerful persona, fans get an almost perfect character with very few flaws. But that’s only the Sung Jinwoo from the manhwa.
The Anime Removes Most of Jinwoo’s Emotional Moments

The anime’s Jinwoo is quite different, lacking many of the traits that add personality to the character. For many fans, these might seem like minor or insignificant changes. But in the bigger picture of storytelling, character development is shaped by these small details. Those expressive moments are what make Jinwoo who he is, and without them, he feels incomplete.
It’s fair to say the anime’s Jinwoo feels quite different from what he’s supposed to be. Of course, the anime adds some unique traits, like making Jinwoo more family-focused, but this aspect also exists in the manhwa, even if it’s less emphasized.
Sung Jinwoo Is Much More Dynamic in the Manhwa

Without a doubt, Sung Jinwoo in the manhwa is much more dynamic. He displays a wide range of emotions that fans can truly feel through every page. This emotional expressiveness is a major quality that the anime’s Jinwoo lacks.
The main character is definitely cool, but because he lacks this emotional depth, it can feel somewhat forced. On the other hand, if Jinwoo had the same expressiveness as in the manhwa, it would be much easier to accept because the mix of emotions makes the character feel more human.
In the end, Solo Leveling remains an extraordinary series, and fans really can’t complain about what the anime has achieved. However, understanding the differences between the two versions of the character is important. Fans who want to see the true Jinwoo should read the manhwa to experience the big personality gap.
