After I Transmigrated into a Book, I Chose a Consort and Lay Low Until the End

Su Yunjin transmigrates into an ancient romance novel.

The good news: She is the emperor's only daughter, undeniably the most powerful second-generation heiress.

The bad news: She is the novel's vicious supporting female character, who bullies the heroine and steals her love interest, only to meet a tragic end.

The even worse news: She has never read the book and knows nothing about the story.

Luckily, she transmigrated at a good time. The story has yet to fully unfold, so there's still room to turn things around.

So she decides to find herself a prince consort. That way, she can avoid competing with the heroine for the male lead, and also avoid being sent off to marry for political reasons.

Then she can happily and safely lie low until the ending.

Su Yunjin hurries to Qingyun Academy and personally picks the candidate she thinks is best suited to become her prince consort.

But why does the frail young man start acting so strangely after they get married?
