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...

Como desapareciste de repente 
pensé que te había pasado algo.
Como desapareciste de repente, pensé que te había pasado algo.
Você me deu um susto, sumindo assim de repente.
