I Am the Nanny of the Villain - Chapter 145:

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

The elder master in Shen’s refused female secretary to maintain his image，thus the girl, who was beautiful and tough, lost her job. Later, she became the secretary of the young master, a playboy.

She fought her way to gain his trust and became his best assistant. However, things changed quietly.

She noticed that he was getting closer and closer and wanted to remind him not to cross the line, but he said, “If we don’t cross the line, how can we fall in love?”
