Trying to find a movie my SO watched on TV
Hello folks, I am looking for a movie, I mean the name of the movie. The plot goes something like this :
Main actress is scared of relationships or something. She meets a guy and offers him to tie him up to bed for a month or something in order for him to prove her his love. So he agrees and gets tied up, finds the key after some time, starts going to work but is coming back every day and is tying himself up so that she wouldn't notice. Not sure how to plot goes on from here. I think it's French or Italian movie, though I could be very wrong.
Any guesses? Thanks in advance.
