How was the French writer, Guy de Maupassant, influenced by Gustave Flaubert?

Guy de Maupassant and Flaubert are both very famous French writers who are also known to have been very close friends. Flaubert would call Maupassant his "protégé" and would give him advice after reading over his rough drafts. For example, “Une Vie” written by Maupassant, has clearly been influenced by Flaubert’s style of writing. Indeed, “Une Vie” (Maupassant) is very similar in terms of structure and narrative style to “Madame Bovary” (Flaubert), both centering around a woman who is unhappy and unsatisfied with her life. Maupassant and Flaubert both belonged to the naturalist school of writers, also called “le mouvement du réalisme”. This means that they chose to center their novels around marginalized characters, who reflect and depict human nature and social issues. The tone they use is very pessimistic and the plots are usually mundane, as the realist novel is not built around a plot but around a character. Therefore, very complicated or incredible plots tend to distract the reader from focusing solely on the main character.  In "Madame Bovary" and "Une Vie" the reader witnesses the evolution of a female character in a male-dominated society and her disillusionment with life, religion and most importantly love. Maupassant and Flaubert, through their characters tackle the taboo subjects of their age such as: marriage, adultery, religion and the female status. Any questions?
