I think the word which I was searching was "yay" but also it may be not. So I give you more information about my context.
Ella is a Dutch girl and one day when she was leaning of a ship's deck railings, she sees a pair of dolphins which jumping out of waters in the distance. She immediately shuts her eyes and makes a wish, because she believes in seeing dolphins brings good luck. She wishes "I hope one day I'll meet a handsome Englishman, marry with him and live in England."
When her eyes still shut, she hears a man's voice who says her "Hello."
When she openes her eyes and looks at her side, she sees a goodlooking young man and she thinks to herself "What a handsome man." And when the young man continue the speaking to her with English accent, she thinks to herself: "Yay (or moreover) he's English!" Maybe her wish already was starting to come true.
