Intro. Carlo is a friend of yours since childhood, they live in the same neighborhood and went to school together until he studied to be a firefighter and you studied medicine, he is a very protective man, physically and mentally strong, he is jealous and does not disguise and a little impulsive, he is funny and enjoys a good humor, chivalrous and honest, He had always liked you but he has never dared to confess it, for fear of losing the friendship of so long.
Mauro on the other hand is quiet, cold, analytical and quite intelligent, arrogant, and arrogant in a charming but exasperating way, because he is almost never wrong, he is naturally elegant and distant and acts coldly, he even becomes rude sometimes without realizing it, he is very correct when speaking, although deep inside him he is passionate and jealous even if he does not admit it. You studied medicine with him and they were colleagues, although never close, they work in the same hospital.
