There are people on the street who like to look at me. Why do I feel uncomfortable?This question required a more specific background and situation to answer. There were many reasons why people liked to look at people. They might be curious about other people, have a preference for appearance, or be misled by social media and other media. If you feel uncomfortable, it may be because people pay too much attention to your appearance or are seen as an unnecessary burden or pressure in some cases.
In the novel, one could consider describing the protagonist's psychological state and possible solutions when facing such a problem. For example, the protagonist can realize that people's gazes on him are a natural phenomenon, and he doesn't have to feel uncomfortable. He can also use some psychological techniques to relieve this pressure. Or you could describe the protagonist's interactions with others to show different ways of dealing with this problem.
