Toward Eternity

In a near-future world, a new technological therapy is quickly eradicating cancer. The body's cells are entirely replaced with nanites - robot or android cells which not only cure those afflicted but leaves them virtually immortal. Literary researcher Yonghun teaches an AI how to understand poetry and creates a living, thinking machine he names Panit, meaning Beloved, in honor of his husband. When Yonghun - himself a recipient of nanotherapy - mysteriously vanishes into thin air and then just as suddenly reappears, the event raises disturbing questions. What happened to Yonghun, and though he's returned, is he really himself anymore?
