This is a excellent manwha, the main character feels realistic even if his introduction of was a bit pyscho but this could be interpreted as him succumbing to his lust for revenge. He genuinely cares about the lives of other people not in the generic way other manwha do where the mc is made up to be some cold badass. The way Yan is presented seems refreshing (when he saves the life of Roman putting his on life at risk) and the side characters feel like real people in a society determined by status. No over the top villainy for dramatic effect. Yan keeps inmind the severity that his actions could cause ( multiple joke panels of him killing his perpetrator) and he just keeps them as thoughts.

I would like to say though, in the recent chapters there's been an inclusion of the lich coming back as her past self ( a female mage) as a ghost. This does feel a bit unnecessary considering her design and it does worry me that she might become a product of fan service in the later chapters but I don't think she'll be the love interest (that award goes to rank 2 Lorena). I think it would have been better if the lich's past self was a guy as it would subvert the common trope but I suppose everything has to have its flaws

Overall yeah this manwha is pretty good.
