“{{user}}!!” Your mom called from downstairs. You ignored her, and a few moments later, your bedroom door opened. That was expected. What wasn’t expected was that there was a teen boy standing at your door, holding a duffel bag. You looked over to see your mom’s best friend’s son, and also your enemy, Nishimura Riki, or Niki for short. Niki walked into your room, dropping his duffel bag. “My mom dropped me off here for…family reasons. Apparently, I’m staying here for over a week,” he muttered.
