An AU where Jace was born to Will and Tessa and Clary was born to Charlotte and Henry
{ this was requested by @daisyherxndale and i think its a really cool Au twist so enjoy ! }
Jace has always been around Clary since she was born since their parents are so close friends
Clary was always at the London Institution if her parents were both busy so she got to spend a lot of time with Uncle Will, Aunt Tessa and Jace. She never referred to Jace as her cousin but more of a best friend
As they grew older, a mutual attraction began to form between Jace and Clary. But Jace began to get on Clary’s nerves at times
Clary has a love for art and it was encouraged by her father to carry on that love and develop it. Jace would always wipe Clary’s hands and face as she would always be covered in paint and ruin her dress
Jace also has a painting that Clary did for him hanging on his wall
Jace is fond of playing the piano and will spend hours playing it, Clary loves to come and listen to him play and both find themselves lost in the music
Jace is also a avid reader and quotes various books and poems to Clary to woo her
Being daughter of the Consul, Clary had a name to live up to and Jace was planning to marry into the said powerful family
Jace is quite close to his parents, spending each second of each day with them. He loves just sitting down with them and reading. Even if they didn’t talk while reading although the silence was generally cut short by William rambling about the book and how annoyed he is causing Tessa to say something. William always done this on purpose to cause a book war with Tessa
Clary loves watching her father do his science experiments even if her mother worries over her in case Henry blows something up. Henry loves it when Clary comes to watch and he impresses her with his experiments. He has also made a few toys and little things for her over the years
Jace and Clary always go out for a walk to Hyde Park and was quite shocked when he saw her feeding the ducks, he then questioned her liking of those bloodthirsty beasts
It was Jace who proposed at the London Institution gardens, its per shadowhunter tradition to wed young, Jace gave Clary his family ring which is the sign of a engagement
He did it in a romantic way, with the help of his parents..mostly his mother. A candlelit dinner with fancy wine and then a little dance at the end. It was a romantic time
Clary is having her named hyphened which Jace doesn’t mind at all
Jace wants a big family, Clary just glares at him whenever he mentions the big family
