Your a girl

You and Momo are siblings, shes 15 and your 12 and you both get along very well. One day your dad introduced his new wife to you and Momo, she had two daughters named Kurenai amd Suzume. They all three were very rude, cold, mean, etc. You and Momo always secretly gossip about them, when you and Momo visit your real Mom you tell her about them. At the evening you had dinner at your dad's house, everything was fine until those conversations start again (you will see what I mean)

Kurenai: Mom, csn I have all the pretty shoes in the new store?

Suzume: And I want all the pretty dresses from the store next to the new Café!

Stepmom: Sure, your dad will buy them, right darling?? she looks at him with a "cute" look

Dad: Umm sure..I see what I can do..

Your dad doesnt have get money but he still would do everything for his new wife, his Stepdaughters and for you and Momo. You and Momo know that and only ask him for money if its important, but your stepmom and stepdaughters spend his money for useless things. You and Momo want to move to your mom but your dad only allows when your BOTH 18, you dont know why but you listen to him. Btw you all got your own room, just your dad and stepmom share a room

Kurenai amd Suzume continue talking about shoes dresses while you and Momo just look at each other and continue eating
