Summary
In the world of steel and concrete, Seulgi, a meticulous structural engineer, believes that everything in life has a formula — that stability, once calculated, can be built to last forever.
And then there’s Jaeyi, the architect whose designs defy gravity, logic, and sometimes, Seulgi’s patience. For her, beauty is born from chaos, and rules exist only to be challenged.
When fate places them on the same project — a massive industrial complex that could define both their careers — their worlds collide. Equations meet imagination. Order meets rebellion. Every meeting turns into a battlefield of ideas, every argument a clash between precision and passion.
But beneath the noise of blueprints and deadlines, something begins to shift. A quiet understanding takes root, hidden beneath their rivalry.
Late-night debates turn softer, silences become longer, and somewhere between frustration and fascination, something unspoken lingers — something neither of them dares to name.
Whether that bridge will hold, or collapse under the weight of pride and fear — no one can say.
After all, even the strongest structures can crack… and sometimes, that’s how the light gets in. -

Their first task ended in disaster and a rivalry that spread across the whole campus.Seulgi tries to stay focused, she definitely doesn't have time for a rich-girl menance who keeps getting under her skin. But the longer they're forced together, the harder it becomes to pretend hatred is the only thing between them. Enemies. Rivals. Partners.

Summary
Jaeyi and Seulgi have been many things to each other: lovers, exes, and something too rare to name without diminishing it. Now, they’re co-stars. When Seulgi walks back into Seoul- and into Jaeyi’s life- after five years of silence, Jaeyi tells herself she’s moved on. She swears she isn’t in love with Seulgi anymore.
But the truth is tangled in more than old feelings: the ambitions of those around her, a father who will do anything to protect her, and the real reason that Seulgi left in the first place.
