Madame Butterfly / Miss Saigon
Isn't this story just an adaptation (some would said plagerization) of Puccini's Madame Butterfly, later adapted into Miss Saigon?
American man in the Orient meets & falls in love with an Asian woman (China, Japan, Vietnam). His friends soon convince him he can't bring her home to America. He departs, not knowing she's pregnant with his child. They meet a few years later, when he's married to an American woman. She gives the child to them to raise and commits suicide.
