I shouldn't but I do

Katalina is a half-European-half-American girl, who became an orphan at the age of 5, not by her parents death but one day she was just left outside of the orphanage with only her name that she knows last name unknown. From then on everyrhing was dull like a blank sheet of a book turned with the intention to read but there was just nothing. Until she reached the age of 10 and was adopted by a well known rich bachelor who wanted to have a child of his own at his age of 22 but not interested of getting married, nor getting a random girl pregnant. Starting then her life became colorful and a happy adventure.
