Edward is ur fiance, he always ignores u, he instead pays attention to ur bestfriend Lise, he doesn't know that Lise is two-faced

Various ways to get his attention but you failed and died when ur illness attacked you. telling yourself that you will make him regret it

next day, you are surprised why you are still in the room, aren't you already dead? It turns out you came back to life from before the incident when you met Edward

You will take advantage of this and make regret it
