The Supporting Actress’s Diary Is Exposed: Lord Marquis, Why Are You Blushing?

[Transmigrated into the Wrong Book + Everyone's Favorite + Playing Dumb to Catch the Tiger + Sweet Romance and Feel-Good Revenge]

She transmigrates into a book as the vicious villainess in a story about a woman adored by everyone, and knows exactly how miserable her ending will be.

What a messed-up life. She can't escape or get very far, so all she can do is vent in her diary about these idiots.

[My lord, the white lotus is here to steal the military plans. Hide them, will you?!]

The marquis really does put the plans away, eventually earning a promotion and a noble title while his household avoids disaster.

[Second brother, don't listen to slander. Save the crown prince first on the battlefield!]

Her second brother really does save the crown prince, rising to become the great general who protects the nation!

[Third brother, don't drink random tea at the banquet, or someone will frame you for making improper advances toward the princess!]

Her third brother really does behave himself and doesn't even touch a drop. In the end, he places first in all three imperial examinations!

[Fourth brother, don't get too close to the Xiongnu when doing business, or you'll be charged with smuggling weapons!]

Her fourth brother really does immediately cut off ties with the Xiongnu. His business flourishes, and he becomes richer than the nation itself.

Even the emperor, the prince, and the minister of the Board of Rites, whom she merely sighed about in her diary, all manage to turn their fates around.

But...

Why are they looking at me so strangely?

This is all off the main plot!

The one everyone is supposed to adore is the female lead, not me. Can you stop mixing us up?

Wait, I get transmigrated into a book, and it's the wrong book? What does that even mean???
