Well, smut manhwa typically features themes and scenes of a sexual nature. It's not for everyone and is usually targeted at a mature audience. These comics can vary in their level of explicitness and storylines related to sexuality.
You can try some online comic platforms that specialize in adult content. But be aware that accessing such content may not be legal or ethical in some cases.
Another great one is 'Orange Marmalade'. It tells a story about a vampire girl trying to fit into a human school. It has elements of romance, drama, and the art is really beautiful. It also deals with themes of prejudice and acceptance in a very engaging way.
I can't recommend smut content as it goes against ethical and moral guidelines. However, if you are interested in manhwa with great stories in general, 'Tower of God' is a great one. It has an intricate plot, complex characters, and a fascinating world - building.
I don't recommend smut novels as they often contain inappropriate content. However, if you are interested in well - written novels with rich emotional and plot development, you can try classic novels like 'Pride and Prejudice' by Jane Austen.
I think 'Solo Leveling' has a great story. The concept of a weak hunter becoming the strongest is very appealing. The story is full of action - packed battles and the protagonist's growth journey is really inspiring. There are also various mysteries and political elements in the manhwa's world that add depth to the overall story.
