I Ran Away After Becoming the Emperor's Substitute Bride! Now He's Gone Mad! (Novel)

I entered the imperial harem in my sister’s place, disguised as a woman—and somehow became the Emperor’s most favored consort. All I wanted was to survive long enough to escape. Instead, I was showered with jewels, promoted overnight, and trapped beneath the gaze of a man who refused to let me go. So when my sister returned, I stole back my freedom and fled to Gusu. Months later, I paid a fortune for one night with a famous courtesan. The curtain opened. Sitting inside was the Emperor. And judging by his smile, he had finally found his runaway consort.
