I don't see why some have added tags that do not fit. The story itself has a sympathetic female lead trying to balance the fate of the world based on the whims of a walking apocalypse, there's nothing typical or cliche about how she and the male lead interact because he is literally a walking disaster, and the reaction to him is what makes the plot so unique. Definitely check it out if you want tension in trying to deal with a being in a story that does a good job in displaying how inhuman such a godlike character would be.

Dropped at chapter 5. The story seems interesting but the translation made it difficult to understand what was going on. Even the translated synopsis is questionable.
