If so, here's the backstory:

They used to date before the whole Forsaken thing happened, but they broke up before then. Before they broke up they were known as the Lovers, some of the most infamous assassins that worked for dangerous people. They got payed heafty amounts of money, but they were young. And stupid. So when they got a request to kill a famed 'witch', they declined. But then found out the client would pay them 8 billion for them to take the witch out. They accepted and went to the address. When they got there, Jaiden was unable to get a clear view from a roof, so Ava had to do it. She snuck in and as she stabbed the witch, they cursed Ava to forever have a demon who craves human as a companion with her always. She brushed it off....till she blacked out and found herself waking up to having bloodied hands and mouth, her mask on the ground next to the witches torn apart body. She quickly finds the bathroom and washes herself. She picks up her knife and mask, then goes back to her lover. This was when they were 20. Timeskip a few years, and the two were finally getting married. Ava's parents kept trying to bribe her to leave Jaiden, as he came from poverty, but she was utterly in love with him. But they wouldn't relent. Eventually, Livet (the demon) gets in her head and makes her black out. When she comes to, she has a black claw, a black tail, and she's covered in blood. She hears a sound....a gun clicking. She looks and sees her own to-be husband pointing a gun at her. He told her how she had eaten not just her own family, but his too. He said she's a monster. She was heartbroken, but stayed strong. He stares at her half human half black face....her left side of the face was black and had a blue eye, which confused him as just seconds ago it was red. But she doesn't tell him about Livet in fear of being called insane any longer and just runs.

Here's Ava's thing:

Avat was in the middle of starving on the streets. Nothing stopped the hunger. She passed out from the hunger. No....he's gonna take control isn't he? Then....when she wakes up, she sees a man. His skin is yellow and some of his face and his arm is black like hers, but his is something different. She realizes then that her mask is gone. She searches for it, then sees that he wasn't scared of her. She asks where she is. He explains where she is and who he is (Mr. Doe/John Doe). Then, a small red kid ran in and hugged this Mr. Doe, calling him Dad. Ava quickly puts her mask back on (John Doe handed it back to her after the explanation). She soon learns the names of the people she's stuck with now, and immediately her and 1x1x1x1 are on each others 'bad sides'. Eventually, her first round. She won no sweat after getting a hang of the powers that came with Livet. Soon, she was being well fed by hunting the survivors and the other killers were like family. She doesn't show or tell any of them about IT though. Only Mister Doe knows about Livet.... And that's how she plans to keep it.

And here's Jaiden's thing:

Jaiden hadn't talked to Ava since the incident. He hasn't even heard anything about her. Hell, he moved to stay away from her. His love was going well, he helped a few people for extra money sometimes, but he also still did assassinations. He was pretty damn rich but only used the money for needs like water, food, and clothes as to not be suspicious. Then, as he fell asleep in his bed one day, he awakens to the smell of....pizza? He sits up and sees multiple people. What. The flip. Why were there others in HIS HOU- wait....he's not in his house. Then, one calls out that the 'newbie' is awake. Another hits the first one and says they need to 'knock it off' and called them Chance. The person walks up to Jaiden, and introduced himself as Elliot. He was the one making pizza. Then the other survivors got introduced. He recognized some of their names. They were missing people. All of them. Only ones he didn't really recognize were the names Noob, Chance, and Two Time. He knew Shedletsky was a retired famous guy who used to make games, Elliot he knew from the Pizzeria he and Ava used to go to, he recognized 007n7 as someone who was blacklisted from the Buildermens pizzeria because of causing too much trouble, and the others were either famous legends or smth else. He then realizes he has his mask on as Elliot asks if they could see his face. Jaiden shakes his head and pulls his hood up. He asks if there's a bedroom for him, and 7n7 leads him to the room. He shuts himself in his room and sees that he has all his stuff; his bed, his posters, his hoodies.....his sniper and ammunition......he decided to ask about where he was, and was explained what this place was by Chance. He nods, and on the first run he was on, the killer was c00lkidd. He sniped c00lkidd 5 times, while Chance just got his gun blowing up in his face 10 times and shot c00lkidd only once. Soon Jaiden became someone who everyone decided to try and befriend, as he was seen as scary....seeing how he never spoke anymore and he always wore and hoodie and mask.

And yes, they do eventually meet, but since Jaiden hates Avat, Avat js blocks him from her mind and eats him whenever she can now 🤭
