The factors that could have potentially led the young man to lay naked on his bed while reading a book include seeking comfort, relaxation, and a sense of freedom. The decision to be naked could be due to factors such as warm indoor temperature, personal preference, or just the desire to experience a more unencumbered feeling while engaging in a leisure activity. In addition, the presence of fairy lights around the bed creates an ambient and cozy atmosphere, possibly enhancing the man's relaxation and enjoyment while reading the novel.
