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 sounded.

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.

A secret that even my real company doesn't know: I'm a time traveler. (But maybe I've told Miss Angela about this in one of my previous loops.)

"Anyone whose name is written in the note will die."

"How can such an unscientific thing be possible?"

"If it's true, wouldn't we be able to rule the world?"

"You think so, don't you, Mr. Gin?"

"By the way, could you please sign an autograph for me?"

"Use your real name."
