Bound By Legacy

In Star City, Oliver Queen and Felicity Smoak have a clever, daring, and enigmatic daughter, Olivia "Liv" Queen, who inherited her father's determination and stealthy intuition, along with her mother's tech genius and quick wit. She's the kind of girl who can disarm a foe with a clever remark while quietly planning the next move, leaving others guessing her next step.
In Central City, Barry Allen and Iris West-Allen raise their adventurous and charming son, Eli Allen, gifted with Barry's scientific curiosity and Iris's charisma.
From childhood, Liv and Eli grow up side by side, training together, teasing each other, and exploring the limits of their abilities. Their friendship is seamless, but as they enter their teenage years, sparks begin to show-subtle touches, playful banter with double meanings, and small hints of jealousy whenever someone else catches the other's attention.
The parents-Oliver, Felicity, Barry, and Iris-notice the signs. Felicity teases Oliver about Liv's sly smirks whenever Eli is around, while Iris nudges Barry about how protective Eli becomes when Liv is near. Both couples exchange knowing smiles, recognizing that their kids' bond is evolving into something deeper.
When a villain capable of manipulating timelines threatens both Star City and Central City, Liv's mix of wit and stealth, combined with Eli's speed and instincts, becomes essential. Their teamwork turns into trust, and trust turns into something more intimate. They risk everything not just for the cities, but for each other.
