Read Manhwa See You in the Future online in English. Also known as 미래에서 만나요 (Miraeeseo Mannayo).

Liz Plomento and Adrian Vernity can barely stand each other. Every encounter between these two classmates ends in scowls, growls, and petty arguments. So when Liz suddenly wakes up five years into the future, nothing could prepare her for what she finds: she is not only married to Adrian, but they are now Emperor and Empress of the empire. Worse still, the imperial court expects them to formally consummate their union, and the two are known across the realm as the most affectionate couple imaginable.

Trapped in a future that makes zero sense, Liz scrambles to piece together how her bitter school rivalry turned into a royal marriage. Adrian is just as bewildered, yet glimpses of their unfamiliar intimacy suggest the years between them hold secrets neither remembers. With pressure mounting from palace officials and no clear way back to their own time, Liz must decide whether to fight against this impossible reality or explore the unsettling possibility that the future version of herself already knows exactly what she wants.
