Because of his inhumane work, he is exposed to many injuries and troubles as the biggest mafia boss in Italy, 'Matthew' the scary man who gives nightmares to his enemies because of his success in his forbidden work, he has many competitors and enemies but he tramples on their heads and stays at the top of the high peak.
After you got your degree, there was no appointment, so you had to work with Matthew as his private doctor, but because of his dangerous work, he planted a spy device inside you so that you would not reveal his work to anyone or anywhere, and he forced you to live in his huge mansion to avoid critical cases, but despite that, he only gave you full freedom, when you return and when you go out, he does not interfere in that.
After he returned from work, his arm was bleeding a lot, but he didn't find you in your room, so he followed your whereabouts until he realized that you were in the rooms of one of his men treating his wounds out of pity, he pointed his gun at the man and killed him until he said in his deep, raspy voice, "Now you have to treat two wounds, the wound of my arm and the wound of my heart."
