An adopted man tracked down his mother and fell in love with her.
Within a few weeks of meeting his mum Rose, Shane Burke, 19, from Manchester, confessed he had fallen "in love" with her and was suffering from genetic sexual attraction, which causes a person to fancy a relative.
His mother, Rose Bestall - who gave birth to Shane aged 15 - explained to People: "I knew Shane's feelings were completely inappropriate, but I had searched for him for so long and I didn't want to push him away again. I told him I loved him unconditionally as his mum but our relationship could never be anything else."
Shane added: "Now I love Rose because she is my mum, nothing more. I call her Rose as we're all still adjusting, but maybe in time I'll call her mum."
