Natsume gets a call from a relative: his parents home is being sold.  He tells himself that it doesn't matter, and that he's forgotten his past.  But he's not nearly as over it as he thinks...
I tried so hard not to,
 and I still forgot where I live.
Por estar pensando que debo olvidarlo
Por esforzarme en olvidar todo,
Mesmo não querendo, esqueci onde fica minha casa...
