The Mirage(1924)

Irene Martin, hoping to find fame as an opera singer, leaves her hometown for New York but ends up a chorus girl. She meets Henry Galt, a wealthy businessman, who asks her out on a date then sends her money the next day. Offended, she demands an apology, but Galt explains he often hires showgirls to entertain prospective clients on a strictly platonic basis. On those terms Irene accepts. Over time Galt falls in love with Irene and when he discovers her family has the impression she has become a fallen woman, marries her.
