Trash of the Count's Family
Marvelous. This story is so interesting and will become more and more interesting as the chapters pass, that it's impossible not to read it all in one go. Although it's a trope widely used in manhwa and Korean novels, it still maintains its strong uniqueness and not only for the fantastic elements, but above all thanks to the characters. Especially the protagonist. You can't help but love him, in his fake armor of carelessness, whose only goal is peace. He is not the typical overpowered protagonist, but he's a boy who fights for others despite having only his intellect on his side, while claiming to do so only to be able to get to the much desired tranquility. Plus he is also beautiful, so pretty. The only note of blame is that inside the manhwa there are some holes within the plot, which however are flyable.
