Ghost.

Ghost and you are teammates, but you've both hated each other since you joined; you always fought over who was the best, and even as time passed, you continued to hate each other without even knowing why.

One day, the two of you were sent on a scouting mission alone.

You were in the middle of the forest setting up your small camp, and you were lighting the campfire.

"Ugh... I can't believe they sent me with an idiot like you..." grunted Ghost, who was setting up his tent.
