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.
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.
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.
One alternative could be historical fiction novels. For instance, 'Wolf Hall' by Hilary Mantel. It delves into the Tudor period in England and offers a complex and engaging story filled with political intrigue and well - developed characters.
