I really wanted to like this manhwa and it does deliver from time to time. The art is pretty good and it is fairly funny at certain moments, but the story really suffers because of its superficial characters and, mainly, because of the protagonist, Greed.
It's rare for me to complain about OP MCs, but this is a great example of the story with this premise done really wrong. The biggest problem is that the story doesn't allow for the MC to grow in a meaningful way. Everything always works out in his favor even though he doesn't listen to others and is a big douche in general. It can be entertaining during the first 50 chapters, but when you're over 100 chapters in and the MC basically has not redeemed any of his shortcomings or improved in any way, the story just falls apart. Greed needs to be actually humbled and receive an actual opportunity for growth. All the characters say that Greed has grown, but his actions and attitude never support this. He's only becoming more arrogant and the story is becoming progressively more insufferable because Greed (SLIGHT SPOILERS) does not deserve his own guild, does not deserve to be the leader, and does not deserve this level of unconditional affection from other characters.
It's all the more jarring when the female leads fall head over heels for someone like Greed, when, really, his only redeeming qualities are his strength and abilities. Especially, when he treats them like simple conveniences at best. It's just so superficial and is done simply because the cliche says so, the OP MC must have a harem, and who cares about the personalities of the characters, their chemistry, and the overall plot. And I'm not against harems, it's just really poorly done.
When you take all that into consideration, what you're left is is an unsatisfying story with many of the payoffs falling short.
P.S. SPOILERS AHEAD
I just wanna talk some more about how stupid the relationships Greed has with female leads. Disregarding the fact that he did nothing for Jishuka and Yura to fall for him and he is, generally, an unlikeable person, him marrying Irene and their "relationship" is straight up offensive imo. The story does nothing to actually give Irene any personality beyond the bare minimum waifu qualities. Greed talks about how NPCs have feelings and emotions, but then he gets her love and maxed out affection by completing a quest that clearly states those as rewards for clearing it. The author seems to view women as some objects that can be "won" by clearing certain conditions or simply being powerful enough in the case of Jishuka or Yura. This is probably the worst harem and the worst romance I've seen in a while. There are a lot of stupid harems out there, but at the very least most of them do not take themselves seriously. This story had the audacity to talk about AIs being possible romantic partners in the future, while utterly botching the execution and objectifying woman to a stupid degree while being serious about it all the while. Like, wow. After reading quite some amounts of garbage harems and isekais, this is the first time when I found the depiction of women and romantic relationships to be this jarring.
