In general, the idea of this manhwa is a series of "scary stories" told by two separate group of ghosts about human desires, their greed, and what they do to achieve it. In all of the stories, the ghosts are similar to their story-counterpart in appearance and all are implied to have been either their main characters or an active part of their own stories. After each story, there is a debate amongst the group to see if they have achieve the desire level of story-telling that relates to the theme of "human greed." The debates, when there are any at all, are disappointing and rather shallow, that mostly agrees with the larger opinions of moral ethics instead of careful consideration to both sides of stories.
Some stories are hit-or-miss in how they capture the theme of "human greed". Surprisingly, the stories mostly have a good red herring or a twist that you would least expect. They usually seem to be a predictable plot until unexpectedly, one character would get "a last laugh." The stories all move at a steady pace with good buildup to the "tragedy" that the characters strike, and they normally last about 6-10 chapters. The characters are all of simple drawing with fantastic color palette schemes that creates a lot of depth and develops the aura of the stories. Overall, I rate it a 5/10 because I feel that generally, it is a good read but some stories, which does not entirely capture the theme, can be slow in pace.
This manhwa is still, however, a recommendation to those who loves thriller and is a fan of one-shot series.
