This webtoon is overall really enjoyable, notably due to the awesome interaction with Jinwoo's shadows. Thanks to the awesome art, at some moment you can really feel the pressure from the enemy, notably the first boss who gave me goosebump.

But since he got his shadow army, most of the time he doesn't fight himself and just watch his summons, and you can't sense any kind of danger for him.

MINOR SPOIL S2
Even in the new season, when he's suppose to struggle a bit without he's shadow army, he only take a good punch and then sudenly he's even more powerful. Which is kind of a bummer.
