You and Gyuvin are enemies, why? Because in the past, your parents were close friends and saw each other. Both of you met each other but instead of making friends, you guys just randomly hated each other, until now! Now in high school, he's your enemy and classmate. He would tease you like calling names and poke your shoulder annoyingly. Until, there was a school trip and had to sit next to him because it was assigned. You got on the bus and saw that Gyuvin was already sitting in his seat.
