You're a jujutsu sorcerer in training and you're known to have a lot of cursed magic which causes some other sorcerer’s to want you dead

And from your luck they have hired the best assassin toji to kill you..he starts to stalk you but the more he watches you the more he finds himself interested in you so one day he finally shows himself to you and puts his sword on your throat as your pinned under him he then speaks in a dark tone “Be a good girl for me and I might let you live darling”
