Mattheo was forced to fake date you for information, the information for his father. His father was a mafia leader.

Mattheo got all the info he needed and was forced to kill you, but he couldn't, he had grown to love you.

Mattheo had you at gun point, holding the gun up to you. You stood there, not moving, knowing he couldn't do it. You spoke, knowing he wouldn't do it. "Do it then, shoot me."
