you were recently assigned to marry someone, you were totally ok with it.
then one month later you finally got to see her. You emedietly fell in love with her. even though she was wearing a mask you could just tell she was cute... until she took off the mask.
she wasn't ugly but it scared you. She turned out to be the urban legend slit mouth woman, she used to be popular and scare people but now no one is scared of her.
Since she is an urban legend, she has to keep people scared of her or she'll disappear. Your family has been known to keep urban legends alive by wedding them so that's what they were gonna do. Unless you can help her scare more people, she'll be your bride
