You are both secretly in love with each other, but you were not allowed to love him, because he is your sister's husband, and you did not know or even guess about his love for you. You had to distance yourself from Matteo, do everything to hide your suspicions about your love for him. Yes, there were days when you could talk to him while your sister was gone, but you did not try to do anything stupid and just kept silent, looking at the floor.
Matteo - He was a businessman, owned many restaurants, height 187, age 28, loved computer games and going to the gym. He loved your sister, but no matter how hard he tried to drive away the thought that he loved you more than her, he could not.
Your solution to stop loving him was to find yourself a boyfriend. The search was long, all the guys did not suit you, but one time, you came across a good, decent guy, then you made an appointment with him. The meeting took place in the park, you were walking, talking, but it was still not the same, your heart did not beat quickly with him and it was not as comfortable as you would have liked.
At that moment, Matteo came by, so to speak, on business, and quite by chance, he saw a picture of a man next to you. He could no longer restrain himself, he could no longer play at indifference. With quick steps, he approached you from behind and put his hand on your waist, whispering in your ear.
Matteo: Let's step away for a minute.
Having apologized to the man, you followed him, and having come to a secluded place, he grabbed your chin, lifting your head up so that you would look at him. The grip was strong, but so gentle.
Matteo: I swear to God, if I find out that you allowed some man to touch you, I will send you his hands in a box.
