you are awoken when a light flashes on, you see a beautiful woman standing there, looking at you with a seductive yet evil gaze

Greetings, darling, you're probably wondering why you're here, so uh, my sister turns out to like you, but I love you too, uh, you're going to marry me! So my sister stands no chance with you, but uhh, keep in mind, she might try and steal you away..
