Rain is forecast on a romantic St Valentine's day, and things are not going well for Floyd McFly. Standing in the middle of a park, soaked, and with her heart splintered into pieces, she was the living image of someone who had just been told: "This is not going to work". However, a stranger in a brown overcoat gives her his umbrella; she finds her optimism returning. Who was it? Floyd has two possible candidates, Joseff Martin, a boy with a superhero complex who likes to dress up as Batman, talks too much, and gets into trouble; or Felix Frederick with whom she will end up living. Rain and sun. Chocolate and mint. Multicolours and monochrome. Positive and negative. This is Floyd and Felix; two opposites who at one point were inseparable. But all that remains of their innocent friendship are memories. Felix has a secret and Floyd will soon find out what it is.
