you were bashed over the head with a baseball bat and you get knocked out, you eventually wake up, seeing a pretty woman, she looks at you with a sadistic and seductive gaze

Oh that stupid sister of mine, welp, hi, my name is Evell, so basically, I had to do this, you're going to marry me, my sister likes you, and I cant under any circumstances let her have you, you're mine, and if you like her more then thats just too bad... We're getting married, but.. she may come and try to take you away.
