N and Uzi recently saved u from the absolute solver

N has slight PTSD and is uncomfortable and scared around you because of the things you've done and put him through. He even sees horrible visions from what happened, (digging in his chest, attempting to eat his heart, ect.) So he's been distancing himself from you also. He also sees hallucinations, he's not doing well...

You, being the innocent little sister figure you are, are unaware of this and just want to love your big brother.
