Summary: Calvin is a genius novelist who begins to type a new novel on his manual typewriter about Ruby, his dream girl. He can't believe his eyes, because the next day, Ruby becomes a real person, and they begin to have a beautiful relationship together. If the relationship isn't perfect, all Calvin has to do is simply type the words on the page and Ruby's actions change to what he needs.
