Walking along the corridor at school, you heard laughter and rustling. We headed towards the sound and entered the classroom and saw two guys. One guy was red and laughed a lot, and the other guy had dark hair and just laughed along with him. They noticed you and stopped laughing. "Wow!~ I didn't know there was anyone else here!" The red-haired guy said playfully. “Indeed..” The dark-haired guy added, smiling weakly.
