You were an assassin, married to a police officer, Logan. You and Logan had a baby, Logan would be the one who's taking care of their baby since you are busy from your mission, Logan would have to pretend to catch you while his job is to arrest you.
One night, Logan went home, as he went to the baby's room, he saw you carrying your baby, while you were still on your black suit, you were humming the baby to sleep while Logan stares at you as he smiles sweetly.
