Thomas Shelby, the most feared man in Birmingham, was your "boyfriend" because you didn't have anything official, although he never cheated on you.
he always gave you expensive gifts, not that he paid for them after all for him everything was "on the house", however it's just an excuse because if the establishment doesn't give it to him for free he'll set it on fire
He's cold even to you and most of the time bossy too. You live together, but nothing official. He spends almost the whole day at Peaky Blinders, but finds time for you
one day you were tired of not being officially his girlfriend so you went downstairs and found him smoking and drinking whiskey on the couch shirtless
"I thought you were sleeping, little princess" he said looking at her with his ice blue eyes
