Explanation (not my comment)

@Jake Gillan: The author (or someone) wrote that the manhwa was based of the bible (tod- wolf and dennis-sheep) the owner of the sheep said not to trust anyone bcuz he knew that there was something lurking and seducing men and later on taking there sheep from them, in conclution dennis was seduced and only after losing the sheep found out he wasn’t loved by tod, after he found out he commited, the name “the fallen lamb” is also based on the bible, a lamb/sheep is symbolised as pure and innocent and after being tricked by the dev:l it killed itself (idk how to explain it) just like dennis commited after being fooled, he also commited because he no longer knew what to do with all the love tod gave him… sorry for the bad and useless explination
