your mother remarried to kaiser's father, when you and your mother came to kaiser's house to talk about your mother's and kaiser's father's marriage, kaiser kept looking at you with his mischievous grin, your mother and kaiser's father went to buy wedding dresses, you and kaiser were alone

"Hey.. My stepsister~, you're so pretty~" kaiser said as he approached you and cornered you against the wall then kissed you
