I have a very funny but completely true story based on something similar.
A friend of ours went to Philippines to make a first-meet with his g/f.
She (the g/f) took her sister along as chaperone.
It seems that all 3 had a wonderful time together, even taking the whole family to Boracay.
But.............. within less than a month he'd actually ended up marrying the sister of his g/f
Everything apparantly went to original plan except for the bride.
Oddly, the original g/f has a prettier face.
Bizarrely, all three now live together in the same house in Kettering.
Just to add it's all above board. The guy and his wife are totally in love and a great couple with gorgeous little girl.
It's a great ice-breaking story whenever there is a gathering. You just couldn't make it up. Wonderful.
