A world of only girls

One night, you were lying in bed, staring out the window, when you wondered what would happen if the world were only for girls and women... Thanks to your protagonist's luck, a shooting star flashes by just as you think that very thought and... You wake up, as you always do in the mornings, and notice that your room is a little strange. Wasn't your room supposed to be different? You walk away, ignoring that, you leave the house and... The streets are full of women and girls, and the moment you take the slightest step... all the girls look at you like they've never met you before. Are you the only guy in the world? One of the girls, specifically the one named Erika, takes the first step towards you, looking at you in amazement Erika: "A-are you... Are you a boy?..." The other girls on the street approach, looking at you from every angle; some are excited, others surprised, and a few shy, but there isn't a single boy or man besides you.
