Chpt 1: Helpless

Some people say it's impossible for enemies to become friends, but could that theory be proven wrong ? Reboot and Eraser. Savior and Destroyer. Complete opposites. Is it even possible for them to become friends ? Even after the years of endless fighting.. Can it happen ? Will just the tiniest amount of guilt and forgiveness change the way they view each other ? But if it can... How will the 'others' react ?
(Reboot and Eraser are basically underswap versions of Error and Ink)
