Ermanno was a tech genius and had a high IQ. He may have been used emotionally and financially. He may have been blinded by Rose's love and looked away from few things she did and lost his self respect by thinking of himself as a phedophil for a long time. But now that he knew he was drugged by Harry and Sofia, he knew better to not trust anyone blind folded.
After all that had happened to him in the past he was determined to be a focused, independent and strong minded person. Not a scattered man who was still trying to understand himself.
He was not like his father and not like his mother either. He knew what he wanted to be. He wanted to be himself.
Ermanno had a photoghaphic memory and never skipped any detail.
His self improvement involved yoga. He practiced medication to keep his mind calm and more focused.
