[Western Crossover] The Whole Family Is Putting on an Act

At twelve, Alina and Jason met after a fight, and from then on they relied on each other to survive in Crime Alley. One day, they were cheated out of their wages by the Penguin and Two-Face, then swindled out of an exorbitant rent by their unscrupulous landlady. In the end, they decided to rob the rich to help the poor and steal the Dark Knight's very expensive-looking tires. Although their plan failed, they were lucky enough to escape their impoverished life. Alina was adopted by Dr. Forger. Jason was adopted by a billionaire. But just when they thought they could have the same happy childhood as ordinary kids, they gradually discovered that their new families were anything but ordinary. "Jason, I think my dad might be a spy." Jason: !!! "Jason, I think my mom might be an assassin." Jason: ??? "Jason, I think Anya might have superpowers!!!" Jason: Uh... "Jason, my dog, " "What, can he see the future?" "Yes, he can see the future!!!" Alina clutched her head and shouted in shock, "Is there even one ordinary person in my family?!" Jason hesitated, then finally blurted out, "Actually, I've got a theory too. I... I think Bruce might be Batman." Alina: "Well, I always thought Alfred wasn't so ordinary either." Jason gave her a deeply approving look. They both worked hard to fit into their new families, trying to become strong enough to protect each other. Then one day, they came face-to-face during a mission. "Wait, you're Robin?!" "Wait, you're the one using the ridiculously stupid name Richgirl?" "Seriously, when did you join the young superheroes' organization?" "When did you join an all-girl superhero team behind my back?!" "Fine, fine. You secretly changed your secret identity and became Red Hood, huh?" "And you, undercover FBI agent, superhero, and information broker? You've got every identity covered, don't you!" 1. Jason/Original Female Character, one-on-one romance, bickering childhood friends and sweethearts. An extra-sweet couple. 2. They grow together, in age and in spirit, so the timeline spans a long period. Nothing dark or tragic; I mainly want to write a Jason who hasn't been messed up by the Joker. 3. The romance starts when they're adults. The story is mostly everyday life, and I'll also write about Jason's school life. 4. A Western Crossover fanfic including Spy x Family and more. No warnings for anything except non-canon BL pairings, which won't appear. Some BL storylines made canon by the official creators won't appear either. No warnings for canon BG pairings. Loid/Yor and Anya/Damian will stay together. 5. A mountain of original worldbuilding. Any out-of-character writing is on me. Completed long DC stories: Jason/Original Female Character: [Western Crossover] Beneath the Mask Jason/Original Female Character: [Western Crossover] Lost Ground Dick/Original Female Character: [Western Crossover] The Disaster of Sakura Saiki Riddler/Original Female Character: [Western Crossover] Who Am I Tim/Original Female Character: [Western Crossover] My Green Tea Boyfriend Theme: Kids should help each other.
