What is the Madame Butterfly archetypal story?

Madame Butterfly archetypal story is:

In Nagasaki, Japan, around 1900, U.S. Navy Captain Pinkerton married a Japanese bride, Qiaoqiao Sang (Butterfly), but Pinkerton was just playing along. Shortly after the wedding, Pinkerton was called home.

Three years later, he came back to Japan with his American wife. When Pinkerton learned that Qiaoqiao Sang had given him a son, he decided to adopt him. Loyal to Pinkerton, Qiaoqiao Sang was so grief-stricken that she told Pinkerton to come back in half an hour to claim the child. She placed an American flag in her son's hand, blindfolded him and killed herself.

Artistic features of Madame Butterfly:

Madame Butterfly has a chamber lyric style. It does not pursue the complex plot and external stage effects but all efforts to portray the psychological activities of the heroine Qiaoqiao Sang. In the play, Puccini directly adopted Japanese folk songs such as "Edo Nihonbashi", "Lion Dance" and "Cherry Blossom" to show Qiaoqiao Sang's identity as a geisha and her naivety, which has a unique musical color.

He also skillfully blends Japanese melodies with Italian styles without giving a sense of incongruity. Giorgio San's aria "A Clear Day" is one of the most popular songs in Puccini's operas and the most common soprano piece in opera selections.

It uses a long declamatory lyrical melody to portray Madame Butterfly's conviction that Pinkerton will return to be happily reunited with her in a delicate and apt way, reflecting Puccini's mastery of operatic coloratura.
