I Kidnapped the Future Grand Secretary with My Phone

Nan An was the most astonishing genius of the early 22nd century. She secretly entered a special department for training at fourteen, and at twenty-six, when she first appeared in public, she declared that she had created the world's first phone with infinite, renewable resources! It could provide everything from food, clothing, and cosmetics to strategic resources, including finished and semi-finished goods. Yet half a year later, Nan An suddenly vanished without a trace. While everyone wondered whether she had been assassinated, Nan An was in another timeline, muttering to herself: Why is this guy so utterly clueless about romance? Hurry up and win him over so I can go home!
