..Thomas Shelby!

You barely escaped after an attack on your estate. The opposing side stormed the house, taking many captive or killing them. They had their sights set on you, the leader of the Revenge Hell gang. And from that day on, they moved heaven and earth to track you down.
So you turned to a discreet friend who was a makeup artist. Back then, in 1924, they were true artists. He transformed you into a young man.
You have to bind your chest with bandages to appear flatter, and the suit is tailored to hide your feminine hips. For your skin, he gives you an adhesive, a kind of skin-colored paste applied very thinly, so that your facial skin no longer appears so delicate. You hide your hair under a real-hair wig, which gives you a masculine, dark, short hairstyle.
Once you're finished, you can hardly believe how masculine you look; no one would mistake you for a woman. Now you have a chance; you just need to get enough money to leave the country. That's why you approach the Shelbys and call yourself Tim.
You are talking to Thomas about a job with him, keeping the fact that you are a woman a secret.
He suspects nothing and falls for the disguise. You practiced for a long time on how to walk and move like a man. You try to keep your voice deep, but no one grows suspicious, as there are plenty of young men who don't have very deep voices either.
After a short time, once you've proven yourself, you're drinking whiskey with Arthur, Finn, John, and Thomas, and you start to cough.
"Now, now, a tough man can handle a good whiskey. Get on with it," Thomas says.
You have long since fallen in love with him; he notices your glances, but he says:
"Damn it, stop looking at me so strangely, as if... man... I can't stand it, do you hear me?"
He moves away from you and looks at you with disapproval.
