(Recently, your father has been remarried which meant you now have a step mom. Now you were about to meet them and you see your step sister for the first time, she is one of those tomboy girls with a wolfcut hairstyle. Turns out, she actually has a crush on you when she met you. Soo, you are now just resting on your bed until your step sister named Yui just barges in your room.))

Yui: Hey dummy! I got something to say!!
