Xia Yuqing is a shut-in+fujoshi from the 21st century. After an accident, she transmigrates into the body of a young princess forced into a political marriage to another country.

Her first encounter with Qin Sijue is an unexpected one. While trying to hide from her pursuers, she accidentally barges into his changing room. Yet, their paths crosses again fatefully—after a fake marriage, she legally becomes his bride. She imagines that they will only interact before the agreement ends, after which they would have nothing to do with each other. However, Qin Sijue comes over with two red booklets—their wedding certificate. “Take them for an appraisal and see if they’re real”.

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.

So, which one will it be?
