After I Transmigrated, I Worried About Getting Exposed Every Day

Mu Lan is an agent for the Space-Time Administration. To complete her missions, she takes on different identities and befriends famous figures from various dynasties. But ever since she met an obscure man from the past, one problem after another has come her way.

The Zhenguan era of the Tang Dynasty:

Yuan Mu was born into a prominent family, yet she haggled with Mu Lan over every last copper coin. Even after Mu Lan paid her back, Yuan Mu kept finding excuses to stay close to her.

When she learned Mu Lan was going to be married, she inexplicably kidnapped her and left her with one warning: "Until I figure out who you are, don't even think about getting married."

Mu Lan's heart skipped a beat. Had her identity as someone who had transmigrated been discovered?

The Xining reforms of the Northern Song Dynasty:

Mu Lan was already dreading going on a mission with a colleague she couldn't stand. Then she ran into Su Shi, the subject of one of her previous missions. More than ten years had passed, yet his appearance hadn't changed at all. How was she supposed to explain away this massive BUG...?

One-on-one romance. The male lead is the same person throughout~

Theme: Everyone has a reason for being here.
