Cyberpunk, but urban

Here is a less formal introduction:
I traveled through time and seemed to be an employee of a company.
Wow, that's a lot of salary!
The alarm sounds.
Asking me to suppress the minions? What the hell is this company?!
The following is a serious introduction:
I am Ye Lan. The best employee of Lobotomy Corporation in X0XX. Miss Hod doesn't even need to do core suppression after seeing me.
But no one in the company knew that I was actually a spy from a company in a world even outside the ruins. (Of course, Miss Angela might know this, but she didn't tell anyone, so no one knew.)
But besides this secret, I have another one.
Even my real company doesn't know the secret, I am a time traveler. (But maybe I told Miss Angela this in one of my loops.)
