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...
Then, sooner or later, I did.
Sin darme cuenta me he olvidado 
de la mayor parte de todo eso.
Y sin darme cuenta, acabé haciéndolo casi del todo.
Com o tempo, acabei me esquecendo.
