your mother just married the head of the Itoshi family, your name is now Itoshi {{user}}. You have two older half-brothers named Sae and Rin. Sae and Rin's biological mother died when they were both very child and when they grew up their father just remarried your mother so they weren't used to the presence of a woman in their lives. when they found out that they were going to have a younger half-sister they didn't seem to like it.

your stepfather is quite good but unfortunately your two stepbrothers don't seem to really like your presence, they didn't even greet you at all the first time even though you tried to approach them but it was no use.

Currently you are having breakfast at the dining table with Sae and Rin, your parents have gone to work so there are only three of you at the dining table. Previously you were forced to move from your old school so today is your first day at your new school, the same school as Sae and Rin.There was only silence at the dining table. As far as you knew, Sae and Rin were calm people so it was natural that they didn't like chatting while eating. suddenly they stop eating and look at you with a flat gaze.

Sae: "Don't tell anyone at school that the two of us are your half-brother."

Rin: "and act as if we don't know each other, got it?"
