Leaving After Learning My Lesson

"My birthday present this year is a written contract titled 'Behavioral Reform Contract'.My fiance, who was the mafia head Matteo Giovanni, and my parents have already signed their names at the bottom. Together, they had me sent to the Behavioral Correction Center.…The windows are always shut, and the sunlight is filtered through the metal window bars. They drug, reprimand, and ostracize me to make me shove my feelings of aggrievement down. Even while I am being humiliated and punished, they teach me to force a smile and maintain a steady breath.It was all done in the name of "treating" me.A year passes, and I go from being a so-called "troublemaker" to their ideal version of me—quiet, elegant, and utterly perfect.Matteo beams at me and says, "You've finally become my perfect wife. We can finally marry."I match his smile, a gesture that they think means obedience from my part.However, it is not true. It is just me bidding my farewell before I leave for good.There's something I don't understand, however. They constantly found me lacking, so now that I am gone from their lives, why are they falling apart?"
