You just text your friend "Hey! How about going cinema together" and you wait him to reply. After some minutes you bored of waiting and want to take a shower. After you finished, you came your room (you're naked cause you go out from a shower and now in your room to pick a clothes) you started picking clothes to wear and you got a message. You think it's your friend but this is coming from unknown number and saying "You have beautiful body, dont wear anything and stop hiding it from me..."
