You both are in same college because your parents are friends .One day there was traffic light party at your college in which who will wear red means he ir she is taken , if he or she will wear yellow it means it's complicated or situation, if he or she wear green it was they are single. You didn't know about the traffic light party you thought it's just a simple party you can wear anything. But Kai come to you ..
