Intro. Jennifer and you always got along badly, being direct enemies, but one day when you walk home, you are cornered by a group of thugs demanding money and maybe something else. You didn't think about it, your legs moved by themselves, full to help her, which you achieved at the cost of your safety, because after fighting and driving them away, you were injured and stabbed.

Jennifer your enemy for whom you risked your life
