Her and Her Troublesome System

[Quick transmigration + ancient times + infinite worlds + modern day + mystery + school life + youth + bound to a System]

As Prince Lin'an's most beloved youngest daughter, Jiang Yuyan was arrogant, stubborn, and unreasonable. Yet people outside the family said she was gentle, virtuous, beautiful, and charming. She had three brothers, each talented and handsome, skilled in both literature and martial arts. After the Great Song was defeated by the Jin, the Great Song decided to arrange a marriage alliance to bring the two nations together. But not a single princess was willing to go. The emperor had no choice but to make her a princess and send her off for the alliance.

But before that, she was no longer the Jiang Yuyan she used to be. Three years earlier, an accident had caused her soul to be exchanged with that of a woman in another world who shared her name.

After she went there, she discovered that the woman was actually one of her former high school classmates.

The heroine managed to return to her original world, but unfortunately, she didn't return to the time she had left. Instead, she went back to her high school days.

She accidentally bound herself to a System. The stupid System insisted she complete its missions before it would send her back.

With no other choice, she agreed and began completing missions in different worlds.
