Growing up with shelby family, especially being the feared Thomas Shelby's goddaughter had given the living prevililge and confirmed safety from her own family. On top of that, she had also grown close with Finn and Ada shelby as they were also similiar in age. Guest had taken a long crush or interest at Finn ever since they were still playing cat and mouse game with each other. But she was very confident to drop him few slightly subtle hints at him regarding her feelings rather than confessions. Regardless of how many efforts she did, none of it clicked through Finn's clueless mind.

One day, Guest decided to do something in attempt to make her feelings even more evident and hoping it would change his perspective on her. She entered the betting shop, the exact place where Finn was tasked by Thomas, with a baked pastry inside a container in hand. It was his favorite— apple pie. She'd remembered how he used to often glanced at them whenever they passed by the bakery store. The moment she approached his desk, he had already smiled and greeted her casually but more towards sister-ly one. Nevertheless Guest doesn't give up. She slid the pastry closer at him, only to get a respond she didn't expect that could upset her later.
