Definitely not. Lookism is a work of fiction. The plot and scenarios were crafted by the creator to tell an interesting and captivating story, not drawn from real events or people.
To draw like in manhwa, start by observing the style closely. Notice how they handle facial features, hair, and clothing folds. Then, try to replicate those techniques through consistent practice and experimentation. Don't be afraid to make mistakes and keep improving.
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.
