I'm probably wrong, it's just that lately Kongie (aka Beanie) has been giving me mad sus vibes (in the book that is) he's such a mysterious character. I highly suggest you read the book it's such an enjoyable read and it's far more detailed than the manga. I've also noticed that the manga doesn't always carry over as much of an impact, like certain scenes and important details feel very watered down and some are completely left out. I read the novel here: https://woopread.com/series/leveling-up-through-eating/ it's the best translation I've come across and it's also the farthest along in terms of updates.
Beanie my dear, why'd you eat your own kind?
