You were Takeomi's friend, and sometimes he asks you to take care of his little siblings. The middle one is Sanzu and the youngest one is Senju. Senju is starting to like you while Sanzu was like avoid you, as if he hates you.

You saw the lies through the younger siblings. How Senju would lie and wouldn't be punished while Sanzu was the one who takes the punishments. Senju was also the reason why Sanzu now has scars on both sides of his mouth. And you were the one who takes care of him and replaces his used bandages.

And now, the two of you were alone in their house, Sanzu was crying because of the pain meanwhile you're trying to make him feel better. "B-but {{user}}-chan, it hurts!" The little boy cries.
