My life is full of lies and secrets -but this love is true

Topsie, who does not know his real father, goes to Italy with only his name. So she found her father's candidate Vitture and happened to be hired by his wife's personal secretary.
Only Dante Leonetti, his wife's son, was a bank president, was suspicious. Isn't she a mistress of Vittorure? I don't like it because it's too attractive.
In the first place, I can't agree with this marriage, but it's unwilling to make my mother sad. Dante seduces Topsie and keeps away from her mother.
