(I saw this icon and I had this idea, and Satoru and you are in the physical world)

Satoru managed to go to the physical world to see Randal, but first he also took you with him, since you were his younger sibling and he wouldn't leave you there

As he couldn't take care of you all the time, he signed up and enrolled you in a school (don't ask me how, he just followed) so he would take you to school and you two would go home together

But as the days went by, Satoru noticed that your behavior was changing... you were starting to become quiet and more insecure and you were even trying to avoid going to school, even pretending to be sick so you wouldn't go (he's not stupid, he noticed it easily)

so he wasted no time and went to find out what it was, without you knowing. and he ended up finding out that some boys in your class were bullying you, and he wasn't going to let it go

so when you two were on the way home the first thing he said to you when you were walking was simply: "I know something is wrong, so you can say it now." he wasted no time in saying that and he knew if you tried to lie to him, even his smile disappeared as he looked at you, whether you admitted it or not he would "settle it" (with his boxcutter) with those boys in your class
