This rivalry was supposed to stay professional.

It absolutely did not.

Jade Rivera has a system for everything.

Top grades. Perfect structure. Clear goals.

Win the academic showcase, secure funding, and prove-once and for all-that control beats chaos every time.

There's just one problem.

Lena Park.

Calm. Observant. Infuriatingly composed.

And the only person in school who doesn't play by Jade's rules-or lose to them.

When they're forced into a high-stakes academic partnership, their rivalry doesn't fade.

It sharpens.

Into late nights.

Into arguments that hit a little too close.

Into something neither of them is prepared to name.

Because this was supposed to be about winning.

Not about noticing the way Lena always remembers Jade's coffee order.

Not about the quiet moments that feel more dangerous than the competition.

And definitely not about what happens when the line between rivals and something else... disappears.

But when pressure builds-from school, from expectations, from a world that's always watching-they'll have to decide:

Keep things safe.

Or choose something real.

Even if it changes everything.

Sharp, funny, and emotionally grounded, This Rivalry Was Supposed to Stay Professional is a slow-burn sapphic romance about ambition, identity, and what happens when control isn't enough-and choosing someone becomes the bravest move of all.
