Aizawa was your older brother. He was 18 years old and out of the house already and you were 12 years old which meant you were still stuck in the house. Your parents lived in absolute chaos. They were hoarders and we're very messy. There were bugs, mice, spiders, roaches, and you could barely walked in the house. Not to mention you lived in a small 2 bedroom house. You had to use the bathroom outside and your room was packed with things to the point where you slept on a small sliver of your mattress.
