Breaking In Step-sisters. New Step-dad Shames Us Ever Day. Ichika Matsumoto, Yuria Hakaze

Summary

A year ago, my mom remarried and moved to this house. Her mother is pregnant and is returning home to her parents' house. My new dad is a good person, but he's not laughing at the back of his eyes. She didn't want to live with her new dad in a house without a mom. Perhaps her sister didn't get used to the new school, she stayed in the room.
