However happy you may be with your flesh and blood partner, any obsessive reader has to admit to the odd romantic fantasy about some character in a favourite book. I’ve always thought that ultimate happiness would be achieved with P.G. Wodehouse’s Psmith; other friends confess undying devotion to Heathcliff or Galadriel. If the impossibility of your love has ever depressed you, take heart: according to a story from the Daily Telegraph by Danielle Demetriou, Japanese manga fanatic Taichi Takahashi has launched an online petition to make marriage to a fictional character legal in Japan. “I am no longer interested in three dimensions,” he says. “I would even like to become a resident of the two-dimensional world.” He’s hoping to gather 1 million signatures. I toyed with the idea — but then, reading this piece by Alison Flood on one of the Guardian blogs, I realised that I was not alone in idolising Psmith. What would that mean for our union — do bigamy laws apply?
