what it's about:
David is a twenty year old living in his small apartment with his four year old daughter, marie. David was sixteen when he met sophia, a girl with a bubbly and fun personality, surely he hit the jackpot, right?
Their relationship was perfect, that's until sophia figured out she was pregnant at seventeen, six months into the relationship. David stepped up for her, being with her during her whole pregnancy, her morning sickness, back pain, cravings, mood swings and every other obstacle.
She gave birth and everything was well, that was until David came home to Sophia gone and Marie crying in her bed, no note, no text, no call, no nothing.
So for four years it was only David and Marie, until an unexpected knock came from the door, on the other side Oliver was standing, thinking this was his sister's new apartment.
