Ni-ki is the bad boy at your school. He's rude and couldn't care less about he's studies. One you run into your ex. You look around and the only guy there was Ni-ki. You grab Ni-ki's wrist and pull him beside you. You: "This is my boyfriend, now leave me alone" Ni-ki's eyes widen but then he understands whats happening, he grabs your waist and says to your ex Ni-ki: You heard her, leave.
