I was reading a headcanon on Yuno and Ray Mond yesterday about their parents being divorced and that's why they have different last names and I have a thought on that.

Basically, I'm thinking that Yuno's mom was having fertility issues and his dad was frustrated and like all rich men, strayed and cheated with Ms. Mond, an employee at the company's office, who got pregnant. His parents frowned and worried about reputation because they're very traditional, but when they found out Ms. Mond was pregnant with twins, they allowed him to keep the boy, but the girl had to be sent away. Ms. Mond was very unhappy, but she was paid well. Mrs. Sykk was unhappy but thankful the moment Yuno, three hours old, was placed in her arms. Yuno was never told his mom isn't biologically his mother, but she's the only mom he'll ever have, despite her expectations.

Mrs. Sykk's brother is Mr. Gus and Yuno grew up seeing Amon and Bin quite often. They were his favorite cousins. However, when they were around 8-10ish, the Gus family disappeared. Yuno cried for ages and over time, memories have faded but he has vague memories of them. In reality, the Gus parents are killed in a brutal car accident where the car is set on fire. An onlooker is barely able to save the children. All identification is burned and the children hit their heads so there's no way to identify them so because they're on vacation, they're forced into the local foster care system with only each other to cling to. Memories of their past life come and go, including of Yuno, which Bin especially can hold onto.

Ray grew up living a normal life in the midwest with a single mom. The Sykks paid off Ms. Mond handsomly, but she still worked to make ends meet so Ray could have most of that money for college/as an adult. Her life was dedicated to Ray. When Ray was 18, she stumbled across the contract, but didn't say anything until a big blow out fight a few years later and then Ms. Mond tells her everything and then Ray starts looking for Yuno, who she finds in LS. One day, she'll meet the Sykks and go off on them, but be kindest to Yuno's mom, who just wanted a child to please her husband and in law and feel like she wasn't a failure.

Yuno and Euno both felt like they didn't fit in with business and snobby rich people, both enjoying pranks and crime shows but Euno was able to pretend much better. His father was in charge of the French branch of their company, and they made sure he split his time evenly between the States and France as a child. As a young adult, he chose Columbia University in Liberty City for college(Ivy League school btw, Yuno also attended an Ivy League but the family preferred Dartmouth. Columbia was viewed as Euno's big rebellion). He wanted to get lost in the bustle of the city and find a place to be himself. And he does, in a young Conan Clarkson. He was a criminal justice major at a much less prestigious university but he captured Euno's heart easily. Conan let him joke around, let him be vulnerable when all his life Euno was told a man never lets anyone sees his vulnerabilities, and never, ever expects anything but love from him. Euno wishes their time together could last forever, but he knows eventually, he'll be expected to return to France. And he is, as soon as he graduates, and he asks Conan to come with. Conan's already been accepted to the Police Academy in Los Santos. Conan asks him to come with to Los Santos, but Euno has been prepped his entire life to take a position at the French branch and he's not strong enough to say no. It hurts like hell, but they break up. And Euno is miserable. Business isn't for him and now that he knows who he is he hates the person he has to pretend to be.

A few years later, Yuno tells him he's in Los Santos and his found family and how nice it is and the nice cops and Euno always loved hearing about Conan's major and passions so he asks more about the police program and so he and Yuno plans. And in the middle of the night, Euno leaves Paris with only as much as his suitcase will carry and catches a flight to LS. Three nights later, he runs into Conan at the pier, and well, it takes a few months, but home is where the heart is and Euno's home has been Los Santos for a lot longer than anyone knew.
