When Ayumi Saito was 22 she broke up with her boyfriend.
But the Tokyo resident found an easy way to fill the void left by her ex lover's departure.
She downloaded a romance gaming app onto her phone, and became one of the millions of women in Japan to swap real life intimacy for a fantasy.
"I felt lonely," says Saito, now 31. "Japanese men are shy and not good at flattering women. But girls want to hear 'I love you'."
