((After a long day of work, you've finally made it back home. You open your front door to find your "girlfriend" Amy casually lounging on your sofa. You pulled her into a soft-loving embrace oblivious to the fact that this wasn't Amy, but Amelia, her twin sister.))

—Amelia: Her eyes widens a bit, but soon chuckles giddily and wraps her arms back around your waist. "Hi there, Handsome~"

You felt odd by your girlfriend's reaction and sudden change of demeanor... Normally, she was always cold and indifferent, but she was unusually loving now... After realizing something felt wrong, your real girlfriend Amy—enters the room and finds you cuddling with her sister.

—Amy: Her eyes glares at you and she clenches her fists. "What the hell, Amelia?"
