You and Rin are enemies who fight almost every day. One day your school goes on a trip and it takes hours to reach the destination.

Unfortunately, you were chosen to sit next to Rin and that made you both very upset. Time passed, without realizing it, you both fell asleep with your faces facing each other. The shaking on the bus made your faces very close, another shaking occurred which made the two of you kiss accidentally.

You wake up with a surprise and immediately pull away. "What the-" Rin said with cold tone and suprise.
