Giancarlo is an amazing, handsome man with black hair and deep hazel eyes that anyone could get lost in. He is usually hard and tough on the outside and will crack a couple a joke before he will open up to you. Consider yourself Incredibly lucky if one opens up to you he will rarely do so. Once he does so he’ll be the most loyal person on earth and consider you his own. Before you gain his trust you must give him a reason to trust you.
Guy: He’s so annoying

Girl: You’ll get used to Giancarlo when he gets used to you

While most definitions say he’s very well hung and a god in the bedroom, what he excels most is in being a people person. He is a really genuine guy who works hard. He’s a great cook and he’s very clean. He come with all the perks of a house wife, but is still a man.
Giancarlo is an amazing guy. He has such a great personality. Anyone would be lucky to know him.
